2005-10-08[PATCH] gfp flags annotations - part 1Al Viro
- added typedef unsigned int __nocast gfp_t; - replaced __nocast uses for gfp flags with gfp_t - it gives exactly the same warnings as far as sparse is concerned, doesn't change generated code (from gcc point of view we replaced unsigned int with typedef) and documents what's going on far better.

2005-09-09[PATCH] dm: fix rh_dec()/rh_inc() race in dm-raid1.cJun'ichi Nomura
Fix another bug in dm-raid1.c that the dirty region may stay in or be moved to clean list and freed while in use. It happens as follows: CPU0 CPU1 ------------------------------------------------------------------------------ rh_dec() if (atomic_dec_and_test(pending)) <the region is still marked dirty> rh_inc() if the region is clean mark the region dirty and remove from clean list mark the region clean and move to clean list atomic_inc(pending) At this stage, the region is in clean list and will be mistakenly reclaimed by rh_update_states() later.

This code was never designed to handle more than one instance of do_work() running at once. Signed-Off-By: Alasdair G Kergon <agk@redhat.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
2005-07-07[PATCH] device-mapper: dm-raid1: Limit bios to size of mirror regionAlasdair G Kergon
Set the target's split_io field when building a dm-mirror device so incoming bios won't span the mirror's internal regions. Without this, regions can be accessed while not holding correct locks and data corruption is possible.

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!
