Merge tag 'for-linus-20130409' of git://git.kernel.dk/linux-block
Pull block fixes from Jens Axboe: "I've got a few smaller fixes queued up for 3.9 that should go in. The major one is the loop regression, the others are nice fixes on their own though. It contains: - Fix for unitialized var in the block sysfs code, courtesy of Arnd and gcc-4.8. - Two fixes for mtip32xx, fixing probe and command timeout. Also a debug measure that could have waited for 3.10, but it's driver only, so I let it slip in. - Revert the loop partition cleanup fix, it could cause a deadlock on auto-teardown as part of umount. The fix is clear, but at this point we just want to revert it and get a real fix in for 3.10." * tag 'for-linus-20130409' of git://git.kernel.dk/linux-block: Revert "loop: cleanup partitions when detaching loop device" mtip32xx: fix two smatch warnings mtip32xx: Add debugfs entry device_status mtip32xx: return 0 from pci probe in case of rebuild mtip32xx: recovery from command timeout block: avoid using uninitialized value in from queue_var_store
