[PATCH 09/11] tools headers: Sync uapi/linux/mount.h with the kernel sources
Posted by Namhyung Kim 1 day, 15 hours ago
To pick up the changes in this cset:

  aefff51e1c2986e1 statmount: retrieve security mount options
  2f4d4503e9e5ab76 statmount: add flag to retrieve unescaped options
  44010543fc8bedad fs: add the ability for statmount() to report the sb_source
  ed9d95f691c29748 fs: add the ability for statmount() to report the fs_subtype

This addresses these perf build warnings:

  Warning: Kernel ABI header differences:
    diff -u tools/perf/trace/beauty/include/uapi/linux/mount.h include/uapi/linux/mount.h

Please see tools/include/uapi/README for further details.
