[PATCH next 1/1] perf beauty socket/prctl_option: Cope with extended regexp complaint by grep

From: Arnaldo Carvalho de Melo
Date: Tue Oct 31 2023 - 11:30:03 EST


Noticed on fedora 38, the extended regexp that so far was ok for both
grep and sed now gets complaints by grep, that says '/' doesn't need to
be escaped with '\'.

So stop using '/' in sed, use '%' instead and remove the \ before / in
the common extended regexp.
