Subject: perf test record+probe_libc_inet_pton.sh: Use "grep -F" instead of obsolescent "fgrep"
X-Git-Tag: v6.6.17~4410^2~62
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=bb6b369cb42737afa4114f371868eb1d858ff36e;p=platform%2Fkernel%2Flinux-rpi.git

perf test record+probe_libc_inet_pton.sh: Use "grep -F" instead of obsolescent "fgrep"

There exists the following warning when executing 'perf test record+probe_libc_inet_pton.sh':

  fgrep: warning: fgrep is obsolescent; using grep -F

This is tested on Fedora 38, the version of grep is 3.8, the latest
version of grep claims the fgrep is obsolete, use "grep -F" instead of
"fgrep" to silence the warning.
