Pull workqueue fixes from Tejun Heo: "So, safe fixes my ass. Commit 8852aac25e79 ("workqueue: mod_delayed_work_on() shouldn't queue timer on 0 delay") had the side-effect of performing delayed_work sanity checks even when @delay is 0, which should be fine for any sane use cases. Unfortunately, megaraid was being overly ingenious. It seemingly wanted to use cancel_delayed_work_sync() before cancel_work_sync() was introduced, but didn't want to waste the space for full delayed_work as it was only going to use 0 @delay. So, it only allocated space for struct work_struct and then cast it to struct delayed_work and passed it into delayed_work functions - truly awesome engineering tradeoff to save some bytes. Xiaotian fixed it by making megraid allocate full delayed_work for now. It should be converted to use work_struct and cancel_work_sync() but I think we better do that after 3.7. I added another commit to change BUG_ON()s in __queue_delayed_work() to WARN_ON_ONCE()s so that the kernel doesn't crash even if there are more such abuses." * 'for-3.7-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/wq: workqueue: convert BUG_ON()s in __queue_delayed_work() to WARN_ON_ONCE()s megaraid: fix BUG_ON() from incorrect use of delayed work
