[PATCH 19/20] xfs: cross-reference realtime bitmap to realtime rmapbt scrubber

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Darrick J. Wong <darrick.wong@xxxxxxxxxx>

When we're checking the realtime rmapbt, cross-reference the entries
with the realtime bitmap too.
