Re: [dm-devel] mirror patches - device failure detection/race fix/deadlock fix

The first 4 patches (0000[1234].patch) are the device failure detection patches. They've been cleaned up a bit from the last time they were posted.

The 'race.patch' fixes a couple race conditions that were a result of the __rh_alloc() function releasing and regrabbing a lock when called.

The 'deadlock.patch' switches all spin_lock calls on the region_lock to spin_lock_irqsave. Without this patch you machine will hang.

The patches apply in the order described, and should apply to kernels 2.6.12 - 2.6.13-rc5.

I've made them all attachments to this e-mail. If people don't like it this way, let me know, and I'll do it lkml style.

I'm an idiot.  :)

The 0000[1234].patch files remain unchanged, but you can forget about the race & deadlock patch files. For fixes to those problems, try this new race patch.

QA has confirmed that this patch has at least taken care of the problems I was trying to address with the other patches...
