Hi all,
This patch series backports a number of patches from master to 6.1.y
to fix `-Wdiscarded-qualifiers` and `-Wnonnull` build issues with
newer glibc versions.
Arnaldo Carvalho de Melo (12):
perf diff: Constify strchr() return variables
perf test bpf: Address error about non-null argument for epoll_pwait
2nd arg
perf trace: Deal with compiler const checks
perf tools: Use const for variables receiving str{str,r?chr}() returns
perf strlist: Don't write to const memory
perf metricgroup: Constify variables storing the result of strchr() on
const tables
perf session: Don't write to memory pointed to a const pointer
perf trace-event: Constify variables storing the result of strchr() on
const tables
perf units: Constify variables storing the result of strchr() on const
tables
perf time-utils: Constify variables storing the result of strchr() on
const tables

This is not the correct way to submit patches for inclusion in the
stable kernel tree. Please read:
https://www.kernel.org/doc/html/latest/process/stable-kernel-rules.html
for how to do this properly.
