Can you reproduce at will? Would be nice to know if it hit the error case,
which is where it would hang.

Hello Jens,

Unfortunately this hang is only triggered sporadically by my tests. Since about four weeks ago I triggered several thousand scsi_remove_host() calls with my https://github.com/bvanassche/srp-test software. This morning was the first time that I ran into a blk-mq related hang.

Thanks,

Bart.
