[PATCH 2/4] common/xfs: create a helper for restoring metadumps to the scratch devs

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

 



From: Darrick J. Wong <djwong@xxxxxxxxxx>

Refactor the open-coded $XFS_MDRESTORE_PROG calls into a proper
_scratch_xfs_mdrestore helper.
