kernel/linux.git/tools/perf/util/rlimit.c, branch v7.1Linux kernel stable tree (mirror)https://git.radix-linux.su/kernel/linux.git/atom?h=v7.12023-10-25T17:02:11+00:00perf evsel: Rename evsel__increase_rlimit to rlimit__increase_nofile2023-10-25T17:02:11+00:00Yang Jihongyangjihong1@huawei.com2023-10-23T03:31:44+00:00urn:sha1:e093a222d7cba1eb6c36887e58ce8a4ff249f1c6
evsel__increase_rlimit() helper does nothing with evsel, and description
of the functionality is inaccurate, rename it and move to util/rlimit.c.
By the way, fix a checkppatch warning about misplaced license tag:
WARNING: Misplaced SPDX-License-Identifier tag - use line 1 instead

No functional change.

perf tools: Introduce rlimit__bump_memlock() helper2019-07-09T17:59:11+00:00Arnaldo Carvalho de Meloacme@redhat.com2019-07-09T17:49:26+00:00urn:sha1:4975223b8156c14f0537dcde1554f050fb4d29bf
Just like the BPF guys did when faced with failures with map creation,
etc, i.e. their solution is:
tools/testing/selftests/bpf/bpf_rlimit.h
For perf use this function in 'perf test' and in 'perf trace'.
Make it bump to 4 times the current value, if it fails twice the current
value and if it still fails, warn that things like BPF map creation may
fail, to help in diagnosing the problem.
