From da531cc46ef16301b1bc5bc74acbaacc628904f5 Mon Sep 17 00:00:00 2001 From: "Darrick J. Wong" Date: Wed, 2 Dec 2020 12:25:44 -0800 Subject: xfs: fix parent pointer scrubber bailing out on unallocated inodes xfs_iget can return -ENOENT for a file that the inobt thinks is allocated but has zeroed mode. This currently causes scrub to exit with an operational error instead of flagging this as a corruption. The end result is that scrub mistakenly reports the ENOENT to the user instead of "directory parent pointer corrupt" like we do for EINVAL.
