The first round of this went into 4.20-rc, but we've still some of
them pending. This patch series converts the remaining drivers to
blk-mq. The ones that support dual paths (like SCSI and DM) have
the non-mq path removed. At the end, legacy IO code and schedulers
are killed off.

This patch series is on top of my for-linus branch. It can also
be bound in my mq-conversions branch.

Hi Jens,

I cloned your mq-conversions branch and ran the block, srp and nvmeof-mp
test groups from the blktests project. The result of these tests on my
setup is the same as with kernel v4.19: except for a few false positive
lockdep complaints, all tests pass. The most recent commit that is
involved in the false positive lockdep complaints I encountered is
87915adc3f0a ("workqueue: re-add lockdep dependencies for flushing").
Patches are being discussed to address these false positives.

Bart.
