2006-07-03[PATCH] lockdep: remove RWSEM_DEBUG remnantsIngo Molnar
RWSEM_DEBUG used to be a printk based 'tracing' facility, probably used for very early prototypes of the rwsem code. Remove it. Signed-off-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
2005-10-29[PATCH] add sem_is_read/write_locked()Rik Van Riel
Add sem_is_read/write_locked functions to the read/write semaphores, along the same lines of the *_is_locked spinlock functions. The swap token tuning patch uses sem_is_read_locked; sem_is_write_locked is added for completeness.

2005-08-23[IA64] Remove rwsem limitation of 32k waitersChristoph Lameter
We ran into the limit with the maximum number of waiters at one of our sites. This patch increases the number of possible waiters from 2^15 to 2^31 by using a long for the counter in struct rw_semaphore. S390 and alpha already do this.

2005-04-16Linux-2.6.12-rc2Linus Torvalds
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!
