Subject: [PATCH v2 13/21] xfsprogs: Add delay context to xfs_da_args
Date: Thu, 5 Sep 2019 15:18:47 -0700 [thread overview]
Message-ID: <20190905221855.17555-14-allison.henderson@oracle.com> (raw)
In-Reply-To: <20190905221855.17555-1-allison.henderson@oracle.com>
This patch adds a new struct xfs_delay_context, which we
will use to keep track of the current state of a delayed
attribute operation.
The flags member is used to track various operations that
are in progress so that we know not to repeat them, and
resume where we left off before EAGAIN was returned to
cycle out the transaction. Other members take the place
of local variables that need to retain their values
across multiple function recalls.
