Merge branch 'for-linus' of git://git.kernel.dk/linux-block
Says Jens: "Time to push off some of the pending items. I really wanted to wait until we had the regression nailed, but alas it's not quite there yet. But I'm very confident that it's "just" a missing expire on exit, so fix from Tejun should be fairly trivial. I'm headed out for a week on the slopes. - Killing the barrier part of mtip32xx. It doesn't really support barriers, and it doesn't need them (writes are fully ordered). - A few fixes from Dan Carpenter, preventing overflows of integer multiplication. - A fixup for loop, fixing a previous commit that didn't quite solve the partial read problem from Dave Young. - A bio integer overflow fix from Kent Overstreet. - Improvement/fix of the door "keep locked" part of the cdrom shared code from Paolo Benzini. - A few cfq fixes from Shaohua Li. - A fix for bsg sysfs warning when removing a file it did not create from Stanislaw Gruszka. - Two fixes for floppy from Vivek, preventing a crash. - A few block core fixes from Tejun. One killing the over-optimized ioc exit path, cleaning that up nicely. Two others fixing an oops on elevator switch, due to calling into the scheduler merge check code without holding the queue lock." * 'for-linus' of git://git.kernel.dk/linux-block: block: fix lockdep warning on io_context release put_io_context() relay: prevent integer overflow in relay_open() loop: zero fill bio instead of return -EIO for partial read bio: don't overflow in bio_get_nr_vecs() floppy: Fix a crash during rmmod floppy: Cleanup disk->queue before caling put_disk() if add_disk() was never called cdrom: move shared static to cdrom_device_info bsg: fix sysfs link remove warning block: don't call elevator callbacks for plug merges block: separate out blk_rq_merge_ok() and blk_try_merge() from elevator functions mtip32xx: removed the irrelevant argument of mtip_hw_submit_io() and the unused member of struct driver_data block: strip out locking optimization in put_io_context() cdrom: use copy_to_user() without the underscores block: fix ioc locking warning block: fix NULL icq_cache reference block,cfq: change code order
