Subject: [PATCH 0/5] kprobes: Bugfix and improvements
Date: Wed,  9 Jun 2021 19:50:14 +0900	[thread overview]
Message-ID: <20210609105019.3626677-1-punitagrawal@gmail.com> (raw)

Hi,

Recently while staring at kprobes code for an unrelated task, I
noticed some opportunities for improving the code.

The first patch fixes a long standing bug in kprobes debug
functionality. The remaining patches (marked RFC) refactor the code to
increase code sharing, improve readability and remove redundancy.

All feedback welcome.

Thanks,
Punit

  kprobe: Simplify prepare_kprobe() by dropping redundant version
  csky: ftrace: Drop duplicate implementation of
    arch_check_ftrace_location()
  kprobes: Make arch_check_ftrace_location static
