Merge tag 'probes-v6.3' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace
Pull kprobes updates from Masami Hiramatsu: - 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 * tag 'probes-v6.3' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace: tracing/eprobe: no need to check for negative ret value for snprintf test_kprobes: Add recursed kprobe test case tracing/probe: add a char type to show the character value of traced arguments selftests/ftrace: Fix probepoint testcase to ignore __pfx_* symbols selftests/ftrace: Fix eprobe syntax test case to check filter support tracing/eprobe: Fix to add filter on eprobe description in README file x86/kprobes: Fix arch_check_optimized_kprobe check within optimized_kprobe range x86/kprobes: Fix __recover_optprobed_insn check optimizing logic kprobes: Fix to handle forcibly unoptimized kprobes on freeing_list
