Export commit stats in file
/sys/fs/btrfs/UUID/commit_stats
with example output like:
commits 123
last_commit_ms 11
max_commit_ms 150
total_commit_ms 2000
The values are in one file so reading them at a single time will give a
more consistent view. The stats are internally tracked in nanoseconds so
the cumulative values should not suffer from rounding errors.
Writing 0 to the file 'commit_stats' will reset max_commit_ms.
Initial values are set at first mount of the filesystem.
