[PATCH 17/58] xfs: advertise metadata directory feature

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

 



From: Darrick J. Wong <djwong@xxxxxxxxxx>

Advertise the existence of the metadata directory feature; this will be
used by scrub to decide if it needs to scan the metadir too.
