Linux-2.6.12-rc2 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!

sched: replace INIT_COMPLETION with reinit_completion For the casual device driver writer, it is hard to remember when to use init_completion (to init a completion structure) or INIT_COMPLETION (to *reinit* a completion structure). Furthermore, while all other completion functions exepct a pointer as a parameter, INIT_COMPLETION does not. To make it easier to remember which function to use and to make code more readable, introduce a new inline function with the proper name and consistent argument type. Update the kernel-doc for init_completion while we are here.

sched: add wait_for_completion_io[_timeout] The only difference between wait_for_completion[_timeout]() and wait_for_completion_io[_timeout]() is that the latter calls io_schedule_timeout() instead of schedule_timeout() so that the caller is accounted as waiting for IO, not just sleeping. These functions can be used for correct iowait time accounting when the completion struct is actually used for waiting for IO (e.g. completion of a bio request in the block layer).

sched: Change wait_for_completion_*_timeout() to return a signed long wait_for_completion_*_timeout() can return: 0: if the wait timed out -ve: if the wait was interrupted +ve: if the completion was completed. As they currently return an 'unsigned long', the last two cases are not easily distinguished which can easily result in buggy code, as is the case for the recently added wait_for_completion_interruptible_timeout() call in net/sunrpc/cache.c So change them both to return 'long'. As MAX_SCHEDULE_TIMEOUT is LONG_MAX, a large +ve return value should never overflow. Signed-off-by: NeilBrown <neilb@suse.de> Cc: Peter Zijlstra <a.p.zijlstra@chello.nl> Cc: J.
