From: Darrick J. Wong <djwong@xxxxxxxxxx> The XFS_SB_FEAT_INCOMPAT_LOG_XATTRS feature bit protects a filesystem from old kernels that do not know how to recover extended attribute log intent items. Make this check mandatory instead of a debugging assert. Fixes: fd920008784ea ("xfs: Set up infrastructure for log attribute replay") Signed-off-by: Darrick J.
