That does not resolve the rmmod race against insmod:
scsi host2: scsi_debug: version 0190 [20200710]
[ 42.213400] dev_size_mb=8, opts=0x0, submit_queues=1, statistics=0
[ 42.217527] scsi 2:0:0:0: Direct-Access Linux scsi_debug 0190
PQ: 0 ANSI: 7
[ 42.223346] scsi 2:0:0:0: Attached scsi generic sg0 type 0
[ 42.282195] scsi host2: scsi_debug: version 0190 [20200710]
[ 42.282195] dev_size_mb=8, opts=0x0, submit_queues=1, statistics=0
[ 42.288169] scsi 2:0:0:0: Direct-Access Linux scsi_debug 0190
PQ: 0 ANSI: 7
[ 42.292122] sd 2:0:0:0: Attached scsi generic sg0 type 0
[ 42.292244] sd 2:0:0:0: Power-on or device reset occurred
[ 42.302288] sd 2:0:0:0: [sda] Spinning up disk...
Then we wait...
[ 44.308213] ...................ready
[ 62.748919] sd 2:0:0:0: [sda] 16384 512-byte logical blocks: (8.39 MB/8.00
MiB)
[ 62.754265] sd 2:0:0:0: [sda] Write Protect is off
[ 62.763253] sd 2:0:0:0: [sda] Write cache: enabled, read cache: enabled,
supports DPO and FUA
[ 62.776965] sd 2:0:0:0: [sda] Optimal transfer size 524288 bytes
[ 62.883817] sd 2:0:0:0: [sda] Attached SCSI disk
And then rmmod still fails.
