* | Documentation: kernel-locking: mutex_trylock cannot be used in interrupt contextStefan Richter2010-08-201-2/+5
|/ | | | | | | | | | | | | | | | | | Chapter 6 is right about mutex_trylock, but chapter 10 wasn't. This error was introduced during semaphore-to-mutex conversion of the Unreliable guide. :-) If user context which performs mutex_lock() or mutex_trylock() is preempted by interrupt context which performs mutex_trylock() on the same mutex instance, a deadlock occurs. This is because these functions do not disable local IRQs when they operate on mutex->wait_lock.

* Remove mention of semaphores from kernel-lockingMatthew Wilcox2008-07-241-33/+24
| | | | | | | | | | Since the consensus seems to be to eliminate semaphores where possible, we shouldn't be educating people about how to use them as locks. Use mutexes instead. Semaphores should be described in a separate document if we end up keeping them. Signed-off-by: Matthew Wilcox <willy@linux.intel.com> Acked-by: Rusty Russell <rusty@rustcorp.com.au>

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!
