* 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>

| | | | | | | | | | | | | | | | | | | Andi Kleen pointed out to me that the kernel locking cheat sheet table entries are unreadable. Make table entries smaller so that pdf and ps output is readable (columns were being overwritten and garbled) by using abbreviations. This allows the tables to fit on one page cleanly.

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!
