Message-Id: <1299662016-7721-1-git-send-email-tj@kernel.org> Date: Wed, 9 Mar 2011 10:13:20 +0100 From: Tejun Heo <tj@...nel.org> To: axboe@...nel.dk, linux-kernel@...r.kernel.org, kay.sievers@...y.org, hch@...radead.org Subject: [PATCHSET] block: Convert block drivers to ->check_events(), take#2 Hello, This is the second take of convert-block-drivers-to-check_events patchset. Other than addition of Acked-by's and rebasing on top of the current block:for-2.6.39/core (df457f845e), nothing really changed. 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. This patchset contains the following sixteen patches. 0001-block-Don-t-implicitly-trigger-event-check-on-disk_u.patch 0002-block-Don-t-check-events-on-close-unless-it-was-bloc.patch 0003-block-Don-t-check-events-while-open-is-in-progress.patch 0004-ide-Convert-to-bdops-check_events.patch 0005-floppy-ami-ata-flop-Convert-to-bdops-check_events.patch 0006-gdrom-viocd-Convert-to-bdops-check_events.patch 0007-paride-Convert-to-bdops-check_events.patch 0008-dac960-Convert-to-bdops-check_events.patch 0009-swim-3-Convert-to-bdops-check_events.patch 0010-ub-Convert-to-bdops-check_events.patch 0011-xsysace-Convert-to-bdops-check_events.patch 0012-i2o_block-Convert-to-bdops-check_events.patch 0013-s390-tape_block-Convert-to-bdops-check_events.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. This patchset is available in the following git branch. git://git.kernel.org/pub/scm/linux/kernel/git/tj/misc.git disk-event-convert HEAD is 7904f29ceb3847e7bb8f3296b406c54b8856de56.
