I have been testing a recent linux-next (which includes this change),

wrote 512 bytes at pos 512 write_size=512
# [ 22.339526] sd 0:0:0:0: [sda] permanent stream count = 5
Is that log really required, especially at info level?
That is a scsi_debug disk - I assume that the relevant io hint feature
is now default enabled there.
Hi John,
How about removing the sd_printk() call mentioned above and adding a
sysfs attribute instead that reports the number of permanent streams?
A sysfs entry sounds reasonable, but I don't know enough about this
stream count to say whether that really is a good idea.
Thanks,
John
