[PATCH v2 00/12] Enable lock context analysis in drivers/block/

Hi Jens,

This patch series enables lock context analysis in all block drivers in the
drivers/block/ directory except DRBD. Please consider these patches for the
next merge window.

Thank you,

Bart.

Changes compared to v1:
 - Moved the DRBD changes into a separate patch series.
 - Combined two patches for the loop driver into a single patch.
 - Also for the loop driver, added a __must_hold() annotation to
   __loop_change_fd() and __loop_configure(). Added a __guarded_by()
   annotation to loop_index_idr.
 - Added a __guarded_by() annotation to nbd_index_idr.
 - Introduced the null_zone locking "class" in the null_blk driver.
 - Fixed the rbd patch description.
 - Added a __cond_acquires() annotation to a new function in the ublk driver.
