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 option. It
exposes kernel profiling information in a binary format for use by readprofile(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.
