workqueue: BH workqueue conversions for v6.9
This pull request contains two patches that convert tasklet users to BH
workqueue - backtractest and usb hcd. DM conversions are being routed
through the respective subsystem tree. Hopefully, the next cycle will see a
lot more conversions.
usb: core: hcd: Convert from tasklet to BH workqueue
The only generic interface to execute asynchronously in the BH context is
tasklet; however, it's marked deprecated and has some design flaws. To
replace tasklets, BH workqueue support was recently added. A BH workqueue
behaves similarly to regular workqueues except that the queued work items
are executed in the BH context.
This patch converts usb hcd from tasklet to BH workqueue.
