Will this change cause trouble to shell scripts that set or read this 
parameter (/sys/module/scsi_mod/parameters/use_blk_mq)? What will the 
impact be on systems where scsi_mod.use_blk_mq=Y is passed by GRUB to 
the kernel at boot time, e.g. because it has been set in the 
GRUB_CMDLINE_LINUX variable in /etc/default/grub?

Thanks,

Bart.
