Subject: [PATCH 21/44] tools headers UAPI: Sync linux/fs.h with the kernel

From: Arnaldo Carvalho de Melo <acme@...hat.com>

To pick up the changes in:

  c553ea4fdf27 ("fs/sync.c: sync_file_range(2) may use WB_SYNC_ALL writeback")

That should be used to beautify the 'sync_file_range' syscall 'flags'
arg.

This silences this perf build warning:

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