[GIT PULL] probes: Updates for 6.3

[Masami Hiramatsu (Google) <mhiramat@kernel.org>]

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.
