Hi Guru,

Any chance you could try this fix that I've staged to send to Linus?
https://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm.git/commit/?h=dm-5.4&id=633b1613b2a49304743c18314bb6e6465c21fd8a

Shiort of that, Nikos: do you happen to have a test scenario that teases
out this deadlock?

Thanks,
Mike
