Subject: [PATCH v24 10/11] xfs: Merge xfs_delattr_context into xfs_attr_item
Date: Tue, 24 Aug 2021 15:44:33 -0700	[thread overview]
Message-ID: <20210824224434.968720-11-allison.henderson@oracle.com> (raw)
In-Reply-To: <20210824224434.968720-1-allison.henderson@oracle.com>

This is a clean up patch that merges xfs_delattr_context into
xfs_attr_item.  Now that the refactoring is complete and the delayed
operation infrastructure is in place, we can combine these to eliminate
the extra struct
