[PATCH v3 2/3] common/filter: factor out expected XFS warnings for mount

[Date Prev] [Date Next] [Thread Prev] [Thread Next] [Date Index] [Thread Index]



1) Move filter_xfs_dmesg from xfs/098 to common/filter, and rename
   it as _filter_mount_dmesg.

2) filter out another expected warning on CONFIG_XFS_DEBUG(without
   CONFIG_XFS_ASSERT_FATAL) build.
