NAME
       /proc/profile - kernel profiling

DESCRIPTION
       /proc/profile (since Linux 2.4)
              This file is present only if the kernel was booted with the profile=1 command-line op‐
              tion.   It exposes kernel profiling information in a binary format for use by readpro‐
              file(1).  Writing (e.g., an empty string) to this file resets the profiling  counters;
              on  some  architectures,  writing  a  binary  integer  "profiling  multiplier" of size
              sizeof(int) sets the profiling interrupt frequency.
