From: Darrick J. Wong <djwong@xxxxxxxxxx> This test deliberate crashes xfs_repair midway through writing metadata to check that NEEDSREPAIR is always triggered by filesystem writes. However, the subsequent scan for the NEEDSREPAIR feature bit prints verifier errors to stderr. On a filesystem with metadata directories, this leads to the test failing with this recorded in the golden output: +Metadata CRC error detected at 0x55c0a2dd0d38, xfs_dir3_block block 0xc0/0x1000 +dir block owner 0x82 doesnt match block 0xbb8cd37e44eb3623 This isn't specific to metadata directories -- any repair crash could leave a metadata structure in a weird state such that starting xfs_db will spray verifier errors. For _check_scratch_xfs_features here, we don't care if the filesystem is corrupt; we /only/ care that the superblock feature bit is set. Route all that noise to devnull. Signed-off-by: Darrick J.
