Subject: [PATCH v13 08/14] xfsprogs: Add xfs_attr_set_deferred and xfs_attr_remove_deferred
Date: Thu, 22 Oct 2020 23:33:00 -0700	[thread overview]
Message-ID: <20201023063306.7441-9-allison.henderson@oracle.com> (raw)
In-Reply-To: <20201023063306.7441-1-allison.henderson@oracle.com>

From: Allison Collins <allison.henderson@oracle.com>

These routines to set up and start a new deferred attribute operations.
These functions are meant to be called by any routine needing to
initiate a deferred attribute operation as opposed to the existing
inline operations. New helper function xfs_attr_item_init also added.
