NAME

       /proc/pid/timerslack_ns - timer slack in nanoseconds

DESCRIPTION

       /proc/pid/timerslack_ns (since Linux 4.6)
              This  file  exposes  the  process's  "current"  timer  slack  value,  expressed  in
              nanoseconds.  The file is writable, allowing the process's timer slack value to  be
              changed.   Writing 0 to this file resets the "current" timer slack to the "default"
              timer slack value.  For further details, see the discussion of PR_SET_TIMERSLACK in
              prctl(2).

              Initially,  permission  to  access  this  file was governed by a ptrace access mode
              PTRACE_MODE_ATTACH_FSCREDS check (see ptrace(2)).  However, this  was  subsequently
              deemed  too  strict a requirement (and had the side effect that requiring a process
              to have the CAP_SYS_PTRACE capability would also allow it to view  and  change  any
              process's  memory).   Therefore,  since  Linux  4.9, only the (weaker) CAP_SYS_NICE
              capability is required to access this file.
