Subject: [PATCH v11 13/26] xfsprogs: Add helper function xfs_attr_node_shrink
Date: Fri, 17 Jul 2020 21:33:29 -0700 [thread overview]
Message-ID: <20200718043342.6432-14-allison.henderson@oracle.com> (raw)
In-Reply-To: <20200718043342.6432-1-allison.henderson@oracle.com>
This patch adds a new helper function xfs_attr_node_shrink used to
shrink an attr name into an inode if it is small enough. This helps to
modularize the greater calling function xfs_attr_node_removename.
