Subject: [PATCH 03/17] Add xfs_attr_set_defered and xfs_attr_remove_defered
Date: Wed, 18 Oct 2017 15:55:19 -0700 [thread overview]
Message-ID: <1508367333-3237-4-git-send-email-allison.henderson@oracle.com> (raw)
In-Reply-To: <1508367333-3237-1-git-send-email-allison.henderson@oracle.com>
These routines set up set and start a new deferred attribute
operation. These functions are meant to be called by other
code needing to initiate a deferred attribute operation. We
will use these routines later in the parent pointer patches.
