Subject: [PATCH 03/19] xfs: don't set XFS_BTCUR_BPRV_WASDEL in xfs_bunmapi
Date: Mon, 18 Sep 2017 08:24:06 -0700 [thread overview]
Message-ID: <20170918152422.24345-4-hch@lst.de> (raw)
In-Reply-To: <20170918152422.24345-1-hch@lst.de>
The XFS_BTCUR_BPRV_WASDEL flag is supposed to indicate that we are
converting a delayed allocation to a real one, which isn't the case
in xfs_bunmapi. Setting it could theoretically lead to misaccounting
here, but it's unlikely that we ever hit it in practice.
