[PATCH 07/12] xfs: scrub the data fork of the realtime inodes

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

 



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

The realtime bitmap and summary inodes live on the metadata device, so
we can scrub their data forks with the regular scrubbers.
