From: Darrick J. Wong <darrick.wong@xxxxxxxxxx> [ Upstream commit ea8439899c0b15a176664df62aff928010fad276 ] Pass the same oldext argument (which contains the existing rmapping's unwritten state) to xfs_rmap_lookup_le_range at the start of xfs_rmap_convert_shared. At this point in the code, flags is zero, which means that we perform lookups using the wrong key.
