Subject: [PATCH 26/27] xfs: cleanup I/O-related buffer flags
Date: Wed, 29 Jun 2011 10:01:35 -0400 [thread overview]
Message-ID: <20110629140341.573417594@bombadil.infradead.org> (raw)
In-Reply-To: 20110629140109.003209430@bombadil.infradead.org
[-- Attachment #1: xfs-buf-cleanup-flags --]
[-- Type: text/plain, Size: 15219 bytes --]
Remove the unused and misnamed _XBF_RUN_QUEUES flag, rename XBF_LOG_BUFFER
to the more fitting XBF_SYNCIO, and split XBF_ORDERED into XBF_FUA and
XBF_FLUSH to allow more fine grained control over the bio flags. Also
cleanup processing of the flags in _xfs_buf_ioapply to make more sense,
and renumber the sparse flag number space to group flags by purpose.
