Subject: [GIT PULL] probes: Updates for 6.3
Hi Linus,
probes updates for 6.3:
- Skip negative return code check for snprintf in eprobe.
- Add recursive call test cases for kprobe unit test
- Add 'char' type to probe events to show it as the character instead of value.
- Update kselftest kprobe-event testcase to ignore '__pfx_' symbols.
- Fix kselftest to check filter on eprobe event correctly.
- Add filter on eprobe to the README file in tracefs.
- Fix optprobes to check whether there is 'under unoptimizing' optprobe when optimizing another kprobe correctly.
- Fix optprobe to check whether there is 'under unoptimizing' optprobe when fetching the original instruction correctly.
- Fix optprobe to free 'forcibly unoptimized' optprobe correctly.
