Subject: [PATCHSET] block: convert block drivers to ->check_events()
Date: Tue, 28 Dec 2010 18:28:56 +0100 [thread overview]
Message-ID: <1293557352-10592-1-git-send-email-tj@kernel.org> (raw)
This patchset converts all in-kernel block drivers from
->media_changed() to ->check_events(). Most conversions are fairly
mechanical. The only notable exceptions are,
* 0014-umem: media_changed was dummy. As ->check_events() can be
omitted, just drop it.
* 0015-pktcdvd: inherits and forwards ->check_events() instead of
->media_changed() from the underlying device.

0002-block-don-t-check-events-on-close-unless-it-was-bloc.patch

0014-umem-drop-dummy-media_changed.patch
0015-pktcdvd-convert-to-bdops-check_events.patch
0016-staging-convert-to-bdops-check_events.patch
0001-0003 prepare for further conversions. Some of the conversions
are not very well behaved in that they may generate spurious events
and allow event polling between event clearing check and the actual
clearing. These three patches modify the disk event check behavior
such that such faults can be tolerated.
0004-0016 convert all block drivers. Conversions are mostly
mechanical, all changes except for one of the staging driver are
compile-tested and ide is verified to behave correctly after the
conversion.
We should be able to remove ->media_changed() in the next devel cycle
once the scsi bits and the block branch get merged.
This patchset is on top of the current linux-2.6-block/event-handling
(fcc57045d53edc35bcce456e60ac4aa802712934) and is available in the
following git branch.
