Hi Linus, please pull from:
git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm
tags/libnvdimm-fixes-5.3-rc2
...to receive a collection of locking and async operations fixes for
v5.3-rc2. These had been soaking in a branch targeting the merge
window, but missed due to a regression hunt. This fixed up version has
otherwise been in -next this past week with no reported issues.
In order to gain confidence in the locking changes the pull also
includes a debug / instrumentation patch to enable lockdep coverage
for libnvdimm subsystem operations that depend on the device_lock for
exclusion. As mentioned in the changelog it is a hack, but it works
and documents the locking expectations of the sub-system in a way that
others can use lockdep to verify. The driver core touches got an ack
from Greg.
Please pull, but I'll understand if you want a resend with the debug
patch dropped.

driver-core, libnvdimm: Let device subsystems add local lockdep
coverage (2019-07-18 16:23:27 -0700)
----------------------------------------------------------------
libnvdimm fixes v5.3-rc2
- Fix duplicate device_unregister() calls (multiple threads competing to
do unregister work when scheduling device removal from a sysfs attribute
of the self-same device).
- Fix badblocks registration order bug. Ensure region badblocks are
initialized in advance of namespace registration.
- Fix a deadlock between the bus lock and probe operations.
- Export device-core infrastructure to coordinate async operations via
the device ->dead state.
- Add device-core infrastructure to validate device_lock() usage with
lockdep.
----------------------------------------------------------------
Dan Williams (7):
drivers/base: Introduce kill_device()
libnvdimm/bus: Prevent duplicate device_unregister() calls
libnvdimm/region: Register badblocks before namespaces
libnvdimm/bus: Prepare the nd_ioctl() path to be re-entrant
libnvdimm/bus: Stop holding nvdimm_bus_list_mutex over __nd_ioctl()
libnvdimm/bus: Fix wait_nvdimm_bus_probe_idle() ABBA deadlock
driver-core, libnvdimm: Let device subsystems add local lockdep coverage
