Subject: [PATCH 08/11] scsi: pm80xx: Pass gfp_t flags to libsas event notifiers
Date: Fri, 18 Dec 2020 21:43:51 +0100
Message-ID: <20201218204354.586951-9-a.darwish@linutronix.de> (raw)
In-Reply-To: <20201218204354.586951-1-a.darwish@linutronix.de>

Use the new libsas event notifiers API, which requires callers to
explicitly pass the gfp_t memory allocation flags.

Call chain analysis, pm8001_hwi.c:

  pm8001_interrupt_handler_msix() || pm8001_interrupt_handler_intx() || pm8001_tasklet()
    -> PM8001_CHIP_DISP->isr() = pm80xx_chip_isr()
      -> process_oq [spin_lock_irqsave(&pm8001_ha->lock, ...)]
        -> process_one_iomb()
          -> mpi_hw_event()
            -> hw_event_sas_phy_up()
              -> pm8001_bytes_dmaed()
            -> hw_event_sata_phy_up
              -> pm8001_bytes_dmaed()

All functions are invoked by process_one_iomb(), which is invoked by the
interrupt service routine and the tasklet handler. A similar call chain
is also found at pm80xx_hwi.c. Pass GFP_ATOMIC.

For pm8001_sas.c, pm8001_phy_control() runs in task context as it calls
wait_for_completion() and msleep().  Pass GFP_KERNEL.
