By removing the code below, we put all the commands for all the types of devices (SAS/SATA) as simple-Q (requeue as the device require) and I am not sure whether it is the intention of this change. -----Original Message----- From: Adam Manzanares [mailto:adam.manzanares@xxxxxxxx] Sent: Thursday, October 13, 2016 1:54 PM To: axboe@xxxxxxxxx; tj@xxxxxxxxxx; dan.j.williams@xxxxxxxxx; hare@xxxxxxx; martin.petersen@xxxxxxxxxx; mchristi@xxxxxxxxxx; toshi.kani@xxxxxxx; ming.lei@xxxxxxxxxxxxx; sathya.prakash@xxxxxxxxxxxx; chaitra.basappa@xxxxxxxxxxxx; suganath-prabu.subramani@xxxxxxxxxxxx Cc: linux-block@xxxxxxxxxxxxxxx; linux-ide@xxxxxxxxxxxxxxx; linux-kernel@xxxxxxxxxxxxxxx; MPT-FusionLinux.pdl@xxxxxxxxxxxx; linux-scsi@xxxxxxxxxxxxxxx; Adam Manzanares; Adam Manzanares Subject: [PATCH v4 2/4] fusion: remove iopriority handling The request priority is now by default coming from the ioc. It was not clear what this code was trying to do based upon the iopriority class or data. The driver should check that a device supports priorities and use them according to the specificiations of ioprio.
