This commit modifies _scratch_xfs_mdrestore() and _xfs_mdrestore() to be able to restore metadump files which contain data from external log devices. The callers of _scratch_xfs_mdrestore() must set the value of $SCRATCH_LOGDEV only when all of the following conditions are met: 1. Metadump is in v2 format. 2. Metadump has contents dumped from an external log device. Signed-off-by: Chandan Babu R Reviewed-by: Darrick J.
