6.6-stable review patch. If anyone has any objections, please let me know.
------------------
From: Andrey Albershteyn <aalbersh@xxxxxxxxxx>
commit 82ef1a5356572219f41f9123ca047259a77bd67b upstream.
In XFS_DAS_NODE_REMOVE_ATTR case, xfs_attr_mode_remove_attr() sets
filter to XFS_ATTR_INCOMPLETE. The filter is then reset in
xfs_attr_complete_op() if XFS_DA_OP_REPLACE operation is performed.
The filter is not reset though if XFS just removes the attribute
(args->value == NULL) with xfs_attr_defer_remove(). attr code goes
to XFS_DAS_DONE state.
Fix this by always resetting XFS_ATTR_INCOMPLETE filter. The replace
operation already resets this filter in anyway and others are
completed at this step hence don't need it.
Fixes: fdaf1bb3cafc ("xfs: ATTR_REPLACE algorithm with LARP enabled needs rework")
