*	dm delay: support barriers	Mikulas Patocka	2009-06-22	1	-2/+4
\| \| \| \| \| \| \|	Flush support for dm-delay target. Signed-off-by: Mikulas Patocka <mpatocka@redhat.com> Signed-off-by: Alasdair G Kergon <agk@redhat.com>
*	block: move bio list helpers into bio.h	Christoph Hellwig	2009-04-15	1	-2/+0
\| \| \| \| \| \| \| \| \|	It's used by DM and MD and generally useful, so move the bio list helpers into bio.h. Signed-off-by: Christoph Hellwig <hch@lst.de> Acked-by: Alasdair G Kergon <agk@redhat.com> Signed-off-by: Jens Axboe <jens.axboe@oracle.com>
*	dm: consolidate target deregistration error handling	Mikulas Patocka	2009-01-06	1	-5/+1
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	Change dm_unregister_target to return void and use BUG() for error reporting. dm_unregister_target can only fail because of programming bug in the target driver. It can't fail because of user's behavior or disk errors. This patch changes unregister_target to return void and use BUG if someone tries to unregister non-registered target or unregister target that is in use. This patch removes code duplication (testing of error codes in all dm targets) and reports bugs in just one place, in dm_unregister_target. In some target drivers, these return codes were ignored, which could lead to a situation where bugs could be missed.

*	dm: remove dm header from targets	Mikulas Patocka	2008-10-21	1	-1/+2
\| \| \| \| \| \| \| \|	Change #include "dm.h" to #include <linux/device-mapper.h> in all targets. Targets should not need direct access to internal DM structures. Signed-off-by: Mikulas Patocka <mpatocka@redhat.com> Signed-off-by: Alasdair G Kergon <agk@redhat.com>
*	dm: bio_list macro renaming	Alasdair G Kergon	2007-10-20	1	-1/+1
\| \| \| \| \| \| \| \|	Remove BIO_LIST and DEFINE_BIO_LIST macros that gain us nothing since contents are initialised to NULL. Cc: Jan Engelhardt <jengelh@linux01.gwdg.de> Signed-off-by: Alasdair G Kergon <agk@redhat.com>
*	dm delay: fix status	Milan Broz	2007-10-20	1	-1/+1
\| \| \| \| \| \| \| \|	Fix missing space in dm-delay target status output if separate read and write delay are configured. Signed-off-by: Milan Broz <mbroz@redhat.com> Signed-off-by: Alasdair G Kergon <agk@redhat.com>
*	dm delay: fix ctr error paths	Dmitry Monakhov	2007-10-20	1	-8/+11
\| \| \| \| \| \| \| \|	Add missing 'dm_put_device' to dm-delay target constructor. Signed-off-by: Dmitry Monakhov <dmonakhov@openvz.org> Signed-off-by: Milan Broz <mbroz@redhat.com> Signed-off-by: Alasdair G Kergon <agk@redhat.com>
*	dm delay: cleanup	Alasdair G Kergon	2007-07-13	1	-7/+5
\| \| \| \| \| \| \| \|	Use setup_timer(). Replace semaphore with mutex. Signed-off-by: Alasdair G Kergon <agk@redhat.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
*	dm: use kmem_cache macro	Alasdair G Kergon	2007-07-13	1	-7/+4
\| \| \| \| \| \| \| \| \| \|	Use new KMEM_CACHE() macro and make the newly-exposed structure names more meaningful. Also remove some superfluous casts and inlines (let a modern compiler be the judge).

*	dm: delay target	Heinz Mauelshagen	2007-05-09	1	-0/+383
	New device-mapper target that can delay I/O (for testing). Reads can be separated from writes, redirected to different underlying devices and delayed by differing amounts of time.
