[PATCH 0/4] scsi: hisi_sas: Switch to use tasklet over threaded irq handling

[Yihang Li]

We found that when the CPU handling the interrupt thread is occupied by
other high-priority processes, the interrupt thread will not be scheduled.
So there is a change to switch the driver to use tasklet over threaded
interrupt handling.

Yihang Li (4):
  scsi: hisi_sas: Use tasklet to process CQ interrupts
  scsi: hisi_sas: replace spin_lock/spin_unlock with
    spin_lock_irqsave/spin_unlock_restore
  scsi: hisi_sas: Remove cond_resched() in bottom half of interrupt
  scsi: hisi_sas: Remove unused hisi_sas_sync_poll_cqs()
