Merge branch 'for-linus' of git://git.kernel.dk/linux-block
Pull follow-up block updates from Jens Axboe:
"Includes the fix from Eric to resolve the infinite loop in looking up
or creating an IO context for an exiting task.
Also a bunch of mtip32xx patches. Fairly trivial stuff. It's fairly
new though, but no point in keeping it out of the tree until 3.6 imho.
I've thrown it through basic testing locally as well, works fine. The
one contentious part is the patch that Greg complained about (sysfs
file with multiple values, should be a debugfs file), which is
perfectly valid, but not a regression from what the file contains now.
That will be fixed up separately."
* 'for-linus' of git://git.kernel.dk/linux-block:
block: avoid infinite loop in get_task_io_context()
mtip32xx: Changes to sysfs entries
mtip32xx: Convert macro definitions for flag bits to enum
mtip32xx: minor performance tweak
mtip32xx: Fix to support more than one sector in exec_drive_command()
mtip32xx: Use plain spinlock for 'cmd_issue_lock'
mtip32xx: Set block queue boundary variables
mtip32xx: Fix to handle TFE for PIO(IOCTL/internal) commands
mtip32xx: Change HDIO_GET_IDENTITY to return stored data
mtip32xx: Set custom timeouts for PIO commands
mtip32xx: fix clearing an incorrect register in mtip_init_port
