dm: remove map_info

2012-12-21T20:23:41Z

dm: zero silently drop discards

2010-08-12T03:14:12Z

Have the zero target silently drop a discard rather than fail the request with -EOPNOTSUPP. Signed-off-by: Mike Snitzer Signed-off-by: Alasdair G Kergon

dm: consolidate target deregistration error handling

2009-01-06T03:04:58Z

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. Signed-off-by: Mikulas Patocka Signed-off-by: Alasdair G Kergon

dm: remove dm header from targets

2008-10-21T16:44:59Z

Change #include "dm.h" to #include in all targets. Targets should not need direct access to internal DM structures. Signed-off-by: Mikulas Patocka Signed-off-by: Alasdair G Kergon

Drop 'size' argument from bio_endio and bi_end_io

2007-10-10T07:25:57Z

As bi_end_io is only called once when the reqeust is complete, the 'size' argument is now redundant. Remove it. Now there is no need for bio_endio to subtract the size completed from bi_size. So don't do that either. While we are at it, change bi_end_io to return void. Signed-off-by: Neil Brown Signed-off-by: Jens Axboe

[PATCH] dm: map and endio symbolic return codes

2006-12-08T16:29:09Z

Update existing targets to use the new symbols for return values from target map and end_io functions. There is no effect on behaviour. Test results: Done build test without errors.

Tidy device-mapper error messages to include context information automatically. Signed-off-by: Alasdair G Kergon Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[PATCH] device-mapper: Some missing statics

This patch makes some needlessly global code static. Signed-Off-By: Alasdair G Kergon Signed-off-by: Adrian Bunk Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

Linux-2.6.12-rc2

2005-04-16T22:20:36Z

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
