2021-10-17scsi: snic: Call scsi_done() directlyBart Van Assche1-19/+14
Conditional statements are faster than indirect calls. Hence call scsi_done() directly. Link: https://lore.kernel.org/r/20211007202923.2174984-72-bvanassche@acm.org Signed-off-by: Bart Van Assche <bvanassche@acm.org> Signed-off-by: Martin K. Petersen <martin.petersen@oracle.com>

2018-10-11scsi: snic: Replace spin_is_locked() with lockdepLance Roy1-2/+2
lockdep_assert_held() is better suited to checking locking requirements, since it won't get confused when someone else holds the lock. This is also a step towards possibly removing spin_is_locked().

2016-04-11snic: Fixing race in the hba reset and IO/TM completionNarsimhulu Musini1-0/+11
While HBA reset is in progress, if IO/TM completion is received for the same IO then IO/TM completion path releases the driver private resources associated with IO. This fix prevents releasing the resources in IO and TM completion path if HBA reset is in progress.
