    Hello James,

    Had you noticed that Damien had asked not to send the "sd_zbc: Write unlock
    zone from sd_uninit_cmnd()" patch to Linus without my "scsi-mq: Always
    unprepare before requeuing a request" patch? A quote from an e-mail from
    Damien (https://www.spinics.net/lists/stable/msg185436.html):

    It means that commit 70e42fd02c46e2aa9ab07b766d418637e3a51de7 "scsi:
    sd_zbc: Write unlock zone from sd_uninit_cmnd()" will need to be
    reverted too as it will not solve the potential deadlock anymore. Bart's
    patch was needed for it to work.

    Bart.
