Merge branch 'fprobe: Introduce fprobe function entry/exit probe'
Masami Hiramatsu says:
====================
Hi,
Here is the 12th version of fprobe. This version fixes a possible gcc-11 issue which
was reported as kretprobes on arm issue, and also I updated the fprobe document.
The previous version (v11) is here[1];
[1] https://lore.kernel.org/all/164701432038.268462.3329725152949938527.stgit@devnote2/T/#u
This series introduces the fprobe, the function entry/exit probe
with multiple probe point support for x86, arm64 and powerpc64le.
This also introduces the rethook for hooking function return as same as
the kretprobe does. This abstraction will help us to generalize the fgraph
tracer, because we can just switch to it from the rethook in fprobe,
depending on the kernel configuration.
The patch [1/12] is from Jiri's series[2].
[2] https://lore.kernel.org/all/20220104080943.113249-1-jolsa@kernel.org/T/#u
And the patch [9/10] adds the FPROBE_FL_KPROBE_SHARED flag for the case
if user wants to share the same code (or share a same resource) on the
fprobe and the kprobes.
I forcibly updated my kprobes/fprobe branch, you can pull this series
from:
https://git.kernel.org/pub/scm/linux/kernel/git/mhiramat/linux.git kprobes/fprobe
Thank you,
