Subject: [PATCH 04/10] xfs: remove an unsafe retry in xfs_bmbt_alloc_block
Date: Thu, 13 Apr 2017 10:05:11 +0200	[thread overview]
Message-ID: <20170413080517.12564-5-hch@lst.de> (raw)
In-Reply-To: <20170413080517.12564-1-hch@lst.de>

We've already reserved all possible required blocks and checked
they are avaible in the same AG.
