 "An usual sync-up for the header files and related code:

   - copy headers that are used for perf trace syscall beautifier

   - update the beautifier scripts according to the changes

   - don't show differences in the headers by default"

* tag 'perf-tools-fixes-for-v7.1-2026-05-18' of git://git.kernel.org/pub/scm/linux/kernel/git/perf/perf-tools:
  perf trace: Update beautifier script for clone flags
  perf trace: Add beautifier script for fsmount flags
  perf build: Add make check-headers target
  perf trace: Sync uapi/linux/sched.h with the kernel source
  perf trace: Sync uapi/linux/mount.h with the kernel source
  perf trace: Sync uapi/linux/fs.h with the kernel source
