Subject: [PATCH 18/47] xfs: refactor redo intent item processing
Date: Wed, 20 Jul 2016 21:58:04 -0700	[thread overview]
Message-ID: <146907708421.25461.405239727630066080.stgit@birch.djwong.org> (raw)
In-Reply-To: <146907695530.25461.3225785294902719773.stgit@birch.djwong.org>

Refactor the EFI intent item recovery (and cancellation) functions
into a general function that scans the AIL and an intent item type
specific handler.  Move the function that recovers a single EFI item
into the extent free item code.  We'll want the generalized function
when we start wiring up more redo item types.
