Revert "dm crypt: use WQ_HIGHPRI for the IO and crypt workqueues" (2019-11-20 17:27:39 -0500)
Please pull, thanks!
Mike
----------------------------------------------------------------
- Fix DM core to disallow stacking request-based DM on partitions.
- Fix DM raid target to properly resync raidset even if bitmap needed
additional pages.
- Fix DM crypt performance regression due to use of WQ_HIGHPRI for the
IO and crypt workqueues.
- Fix DM integrity metadata layout that was aligned on 128K boundary
rather than the intended 4K boundary (removes 124K of wasted space for
each metadata block).
- Improve the DM thin, cache and clone targets to use spin_lock_irq
rather than spin_lock_irqsave where possible.
- Fix DM thin single thread performance that was lost due to needless
workqueue wakeups.
- Fix DM zoned target performance that was lost due to excessive backing
device checks.
- Add ability to trigger write failure with the DM dust test target.
- Fix whitespace indentation in drivers/md/Kconfig.
- Various smalls fixes and cleanups (e.g. use struct_size, fix
uninitialized variable, variable renames, etc).
