- * /proc/[pid]/oom_score_adj (since Linux 2.6.36)
- *
- * This file can be used to adjust the badness heuristic used to select which process gets
- * killed in out-of-memory conditions.
- *
- * The badness heuristic assigns a value to each candidate task ranging from 0 (never kill) to
- * 1000 (always kill) to determine which process is targeted. The units are roughly a proportion
- * along that range of allowed memory the process may allocate from, based on an estimation of
- * its current memory and swap use. For example, if a task is using all allowed memory, its
- * badness score will be 1000. If it is using half of its allowed memory, its score will be
- * 500.
- *
- * There is an additional factor included in the badness score: root processes are given 3%
- * extra memory over other tasks.
- *
- * The amount of "allowed" memory depends on the context in which the OOM-killer was called.
- * If it is due to the memory assigned to the allocating task's cpuset being exhausted, the
- * allowed memory represents the set of mems assigned to that cpuset (see cpuset(7)). If it is
- * due to a mempolicy's node(s) being exhausted, the allowed memory represents the set of
- * mempolicy nodes. If it is due to a memory limit (or swap limit) being reached, the allowed
- * memory is that configured limit. Finally, if it is due to the entire system being out of
- * memory, the allowed memory represents all allocatable resources.
- *
- * The value of oom_score_adj is added to the badness score before it is used to determine
- * which task to kill. Acceptable values range from -1000 (OOM_SCORE_ADJ_MIN) to +1000
- * (OOM_SCORE_ADJ_MAX). This allows user space to control the preference for OOM-killing, ranging
- * from always preferring a certain task or completely disabling it from OOM killing. The lowest
- * possible value, -1000, is equivalent to disabling OOM- killing entirely for that task, since
- * it will always report a badness score of 0.
- *
- * Consequently, it is very simple for user space to define the amount of memory to consider
- * for each task. Setting a oom_score_adj value of +500, for example, is roughly equivalent to
- * allowing the remainder of tasks sharing the same system, cpuset, mempolicy, or memory
- * controller resources to use at least 50% more memory. A value of -500, on the other hand,
- * would be roughly equivalent to discounting 50% of the task's allowed memory from being
- * considered as scoring against the task.
- *
- * For backward compatibility with previous kernels, /proc/[pid]/oom_adj can still be used to
- * tune the badness score. Its value is scaled linearly with oom_score_adj.
- *
- * Writing to /proc/[pid]/oom_score_adj or /proc/[pid]/oom_adj will change the other with its
- * scaled value.

- *
- * Status information about the process. This is used by ps(1). It is defined in the kernel
- * source file fs/proc/array.c.
- *
- * The fields, in order, with their proper scanf(3) format specifiers, are:
- *
- *
- * - pid %d The process ID.
- * - comm %s The filename of the executable, in parentheses. This is visible whether or not
- * the executable is swapped out.
- * - state %c One of the following characters, indicating process state:
- *
- * - R Running
- * - S Sleeping in an interruptible wait
- * - D Waiting in uninterruptible disk sleep
- * - Z Zombie
- * - T Stopped (on a signal) or (before Linux 2.6.33) trace stopped
- * - t Tracing stop (Linux 2.6.33 onward)
- * - W Paging (only before Linux 2.6.0)
- * - X Dead (from Linux 2.6.0 onward)
- * - x Dead (Linux 2.6.33 to 3.13 only)
- * - K Wakekill (Linux 2.6.33 to 3.13 only)
- * - W Waking (Linux 2.6.33 to 3.13 only)
- * - P Parked (Linux 3.9 to 3.13 only)
- *
- *
- * - ppid %d The PID of the parent of this process.
- * - pgrp %d The process group ID of the process.
- * - session %d The session ID of the process.
- * - tty_nr %d The controlling terminal of the process. (The minor device number is contained
- * in the combination of bits 31 to 20 and 7 to 0; the major device number is in bits 15 to 8.)
- *
- * - tpgid %d The ID of the foreground process group of the controlling terminal of the
- * process.
- * - flags %u The kernel flags word of the process. For bit meanings, see the PF_* defines in
- * the Linux kernel source file include/linux/sched.h. Details depend on the kernel version.
- * The format for this field was %lu before Linux 2.6.
- * - minflt %lu The number of minor faults the process has made which have not required
- * loading a memory page from disk.
- * - cminflt %lu The number of minor faults that the process's waited-for children have
- * made
- * - majflt %lu The number of major faults the process has made which have required loading a
- * memory page from disk.
- * - cmajflt %lu The number of major faults that the process's waited-for children have
- * made
- * - utime %lu Amount of time that this process has been scheduled in user mode, measured in
- * clock ticks (divide by sysconf(_SC_CLK_TCK)). This includes guest time, guest_time (time
- * spent running a virtual CPU, see below), so that applications that are not aware of the guest
- * time field do not lose that time from their calculations.
- * - stime %lu Amount of time that this process has been scheduled in kernel mode, measured
- * in clock ticks (divide by sysconf(_SC_CLK_TCK)).
- * - cutime %ld Amount of time that this process's waited-for children have been scheduled in
- * user mode, measured in clock ticks (divide by sysconf(_SC_CLK_TCK)). (See also times(2).)
- * This includes guest time, cguest_time (time spent running a virtual CPU, see below).
- * - cstime %ld Amount of time that this process's waited-for children have been scheduled in
- * kernel mode, measured in clock ticks (divide by sysconf(_SC_CLK_TCK)).
- * - priority %ld (Explanation for Linux 2.6) For processes running a real-time scheduling
- * policy (policy below; see sched_setscheduler(2)), this is the negated scheduling priority,
- * minus one; that is, a number in the range -2 to -100, corresponding to real-time priorities 1
- * to 99. For processes running under a non-real-time scheduling policy, this is the raw nice
- * value (setpriority(2)) as represented in the kernel. The kernel stores nice values as numbers
- * in the range 0 (high) to 39 (low), corresponding to the user-visible nice range of -20 to 19.
- * Before Linux 2.6, this was a scaled value based on the scheduler weighting given to this
- * process
- * - nice %ld The nice value (see setpriority(2)), a value in the range 19 (low priority) to
- * -20 (high priority).
- * - num_threads %ld Number of threads in this process (since Linux 2.6). Before kernel 2.6,
- * this field was hard coded to 0 as a placeholder for an earlier removed field.
- * - itrealvalue %ld The time in jiffies before the next SIGALRM is sent to the process due
- * to an interval timer. Since kernel 2.6.17, this field is no longer maintained, and is hard
- * coded as 0.
- * - starttime %llu The time the process started after system boot. In kernels before Linux
- * 2.6, this value was expressed in jiffies. Since Linux 2.6, the value is expressed in clock
- * ticks (divide by sysconf(_SC_CLK_TCK)).
- * - The format for this field was %lu before Linux 2.6. (23) vsize %lu Virtual memory size
- * in bytes.
- * - rss %ld Resident Set Size: number of pages the process has in real memory. This is just
- * the pages which count toward text, data, or stack space. This does not include pages which
- * have not been demand-loaded in, or which are swapped out.
- * - rsslim %lu Current soft limit in bytes on the rss of the process; see the description of
- * RLIMIT_RSS in getrlimit(2).
- * - startcode %lu The address above which program text can run.
- * - endcode %lu The address below which program text can run.
- * - startstack %lu The address of the start (i.e., bottom) of the stack.
- * - kstkesp %lu The current value of ESP (stack pointer), as found in the kernel stack page
- * for the process.
- * - kstkeip %lu The current EIP (instruction pointer).
- * - signal %lu The bitmap of pending signals, displayed as a decimal number. Obsolete,
- * because it does not provide information on real-time signals; use /proc/[pid]/status
- * instead
- * - blocked %lu The bitmap of blocked signals, displayed as a decimal number. Obsolete,
- * because it does not provide information on real-time signals; use /proc/[pid]/status
- * instead
- * - sigignore %lu The bitmap of ignored signals, displayed as a decimal number. Obsolete,
- * because it does not provide information on real-time signals; use /proc/[pid]/status
- * instead
- * - sigcatch %lu The bitmap of caught signals, displayed as a decimal number. Obsolete,
- * because it does not provide information on real-time signals; use /proc/[pid]/status
- * instead.
- * - wchan %lu This is the "channel" in which the process is waiting. It is the address of a
- * location in the kernel where the process is sleeping. The corresponding symbolic name can be
- * found in /proc/[pid]/wchan.
- * - nswap %lu Number of pages swapped (not maintained).
- * - cnswap %lu Cumulative nswap for child processes (not maintained).
- * - exit_signal %d (since Linux 2.1.22) Signal to be sent to parent when we die.
- * - processor %d (since Linux 2.2.8) CPU number last executed on.
- * - rt_priority %u (since Linux 2.5.19) Real-time scheduling priority, a number in the
- * range 1 to 99 for processes scheduled under a real-time policy, or 0, for non-real-time
- * processes (see sched_setscheduler(2)).
- * - policy %u (since Linux 2.5.19) Scheduling policy (see sched_setscheduler(2)). Decode
- * using the SCHED_* constants in linux/sched.h. The format for this field was %lu before Linux
- * 2.6.22.
- * - delayacct_blkio_ticks %llu (since Linux 2.6.18) Aggregated block I/O delays, measured
- * in clock ticks (centiseconds).
- * - guest_time %lu (since Linux 2.6.24) Guest time of the process (time spent running a
- * virtual CPU for a guest operating system), measured in clock ticks (divide by
- * sysconf(_SC_CLK_TCK)).
- * - cguest_time %ld (since Linux 2.6.24) Guest time of the process's children, measured in
- * clock ticks (divide by sysconf(_SC_CLK_TCK)).
- * - start_data %lu (since Linux 3.3) Address above which program initialized and
- * uninitialized (BSS) data are placed.
- * - end_data %lu (since Linux 3.3) Address below which program initialized and
- * uninitialized (BSS) data are placed.
- * - start_brk %lu (since Linux 3.3) Address above which program heap can be expanded with
- * brk(2).
- * - arg_start %lu (since Linux 3.5) Address above which program command-line arguments
- * (argv) are placed.
- * - arg_end %lu (since Linux 3.5) Address below program command-line arguments (argv) are
- * placed.
- * - env_start %lu (since Linux 3.5) Address above which program environment is placed.
- * - env_end %lu (since Linux 3.5) Address below which program environment is placed.
- * - exit_code %d (since Linux 3.5) The thread's exit status in the form reported by
- * waitpid(2).
