Subject: [RFC PATCH 05/11] xfs: update ifree transaction reservations for finobt
Date: Tue, 3 Sep 2013 14:25:02 -0400 [thread overview]
Message-ID: <1378232708-57156-6-git-send-email-bfoster@redhat.com> (raw)
In-Reply-To: <1378232708-57156-1-git-send-email-bfoster@redhat.com>
Update the ifree transaction log reservations to support the
finobt. An inode free can now mean an extra record modification,
record removal (i.e., inode chunk being freed) or a record
insertion (i.e., a previously full inode chunk).
Define XFS_IFREE_SPACE_RES() for the inactive transaction to
reserve data blocks for possible finobt merge/split situations.
