I copied /fs/ext4 from tree 4.18.20 to tree 4.19.5
and compile everything from scratch the tree 4.19.5.
Well, now we'll have to wait and cross our fingers every time I restart the PC.
So far I had no problems, if they appear I would be posted again with data.
Regarding my configuration of CONFIG_SCSI_MQ_DEFAULT it was always enabled for
eons.

# cat /boot/config-4.18.20-gentoo |grep CONFIG_SCSI_MQ_DEFAULT=
CONFIG_SCSI_MQ_DEFAULT=y
# cat /boot/config-4.19.4-gentoo |grep CONFIG_SCSI_MQ_DEFAULT=
CONFIG_SCSI_MQ_DEFAULT=y
# cat /boot/config-4.19.5-gentoo |grep CONFIG_SCSI_MQ_DEFAULT=
CONFIG_SCSI_MQ_DEFAULT=y

# eix -Ic e2fsprogs
