Revision 4faa5285283fad081443e3612ca426a311bb6c7e authored by Zach Brown on 17 October 2005, 23:43:33 UTC, committed by Linus Torvalds on 18 October 2005, 00:03:57 UTC
lock_kiocb() was introduced to serialize retrying and cancellation.  In the
process of doing so it tried to sleep waiting for KIF_LOCKED while holding
the ctx_lock spinlock.  Recent fixes have ensured that multiple concurrent
retries won't be attempted for a given iocb.  Cancel has other problems and
has no significant in-tree users that have been complaining about it.  So
for the immediate future we'll revert sleeping with the lock held and will
address proper cancellation and retry serialization in the future.
