xfs: track usage statistics of online fsck
Track the usage, outcomes, and run times of the online fsck code, and
report these values via debugfs. The columns in the file are:
* scrubber name
* number of scrub invocations
* clean objects found
* corruptions found
* optimizations found
* cross referencing failures
* inconsistencies found during cross referencing
* incomplete scrubs
* warnings
* number of time scrub had to retry
* cumulative amount of time spent scrubbing (microseconds)
* number of repair inovcations
* successfully repaired objects
* cumuluative amount of time spent repairing (microseconds)
