ide-cd: fix DMA alignment regression

2008-11-02T20:40:07+00:00

e5318b531b008c79d2a0c0df06a7b8628da38e2f ("ide: use the dma safe check for
REQ_TYPE_ATA_PC") introduced a regression which caused some ATAPI drives to
turn off DMA for REQ_TYPE_BLOCK_PC commands while burning and thus degrading
performance and ultimately causing an excessive amount of underruns.

The issue is documented also in:
http://bugzilla.kernel.org/show_bug.cgi?id=11742.

ide-cd: add TEAC CD-224E to the NO_AUTOCLOSE list

2008-10-23T21:22:09+00:00

The "TEAC CD-ROM CD-224E" cannot close its tray, so add it to the NO_AUTOCLOSE
list. This will correct the "Can close tray" field of /proc/sys/dev/cdrom/info.

[PATCH] beginning of methods conversion

2008-10-21T11:47:32+00:00

To keep the size of changesets sane we split the switch by drivers;
to keep the damn thing bisectable we do the following:
	1) rename the affected methods, add ones with correct
prototypes, make (few) callers handle both.  That's this changeset.
	2) for each driver convert to new methods.  *ALL* drivers
are converted in this series.
	3) kill the old (renamed) methods.

Note that it _is_ a flagday; all in-tree drivers are converted and by the
end of this series no trace of old methods remain.  The only reason why
we do that this way is to keep the damn thing bisectable and allow per-driver
debugging if anything goes wrong.

New methods:
	open(bdev, mode)
	release(disk, mode)
	ioctl(bdev, mode, cmd, arg)		/* Called without BKL */
	compat_ioctl(bdev, mode, cmd, arg)
	locked_ioctl(bdev, mode, cmd, arg)	/* Called with BKL, legacy */

ide-cd: debug log enhancements

Add some more verbosity to key function calls in ide-cd debug code. While at it,
delete a superfluous comment.
