Subject: tools headers UAPI: Sync linux/prctl.h with the kernel sources
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=71852cd8825077d2d90466ac34d3b94e0be3bfae;p=linux.git

tools headers UAPI: Sync linux/prctl.h with the kernel sources

  ddc65971bb677aa9 ("prctl: add PR_GET_AUXV to copy auxv to userspace")

To pick the changes in:

That don't result in any changes in tooling:

  $ tools/perf/trace/beauty/prctl_option.sh > before
  $ cp include/uapi/linux/prctl.h tools/include/uapi/linux/prctl.h
  $ tools/perf/trace/beauty/prctl_option.sh > after
  $ diff -u before after
  $

This actually adds a new prctl arg, but it has to be dealt with
differently, as it is not in sequence with the other arguments.

Just silences this perf tools build warning:

  Warning: Kernel ABI header at 'tools/include/uapi/linux/prctl.h' differs from latest version at 'include/uapi/linux/prctl.h'
  diff -u tools/include/uapi/linux/prctl.h include/uapi/linux/prctl.h
