Subject: [Bug 200951] kernel NULL pointer dereference in update_sit_entry
Date: Mon, 03 Sep 2018 09:35:24 +0000 [thread overview]

--- Comment #12 from vicencb@gmail.com ---
As stated in the bug description, there is an udev rule to set
the provisioning_mode attribute to unmap. When searching for
this attribute name, i found this:
drivers/scsi/sd.c:749
blk_queue_max_discard_sectors(q, ...);
blk_queue_flag_set(QUEUE_FLAG_DISCARD, q);
So, it looks like the answer is yes, there is an interface to
turn on discard of device in real time.
Regards,
Vicenç.
