These callbacks are fixed and so there is no reason why the functions cannot be called directly, so do that. This neatens the code slightly, makes it more obvious, and reduces function pointer usage, which is generally a good thing. Downside is that there are 2x more symbol exports.

The usage of in_interrupt() in drivers is phased out and Linus clearly requested that code which changes behaviour depending on context should either be separated or the context be conveyed in an argument passed by the caller, which usually knows the context. The in_interrupt() check is also only partially correct, because it fails to choose the correct code path when just preemption or interrupts are disabled. For example, as in the following call chain: mvsas/mv_sas.c: mvs_work_queue() [process context] spin_lock_irqsave(mvs_info::lock, ) -> libsas/sas_event.c: sas_notify_phy_event() -> sas_alloc_event() -> in_interrupt() = false -> invalid GFP_KERNEL allocation -> libsas/sas_event.c: sas_notify_port_event() -> sas_alloc_event() -> in_interrupt() = false -> invalid GFP_KERNEL allocation Introduce sas_alloc_event_gfp(), sas_notify_port_event_gfp(), and sas_notify_phy_event_gfp(), which all behave like the non _gfp() variants but use a caller-passed GFP mask for allocations. For bisectability, all callers will be modified first to pass GFP context, then the non _gfp() libsas API variants will be modified to take a gfp_t by default.

The only exception, marked with "(+)", is a PCI ->remove() and PM_OPS ->suspend() cold path. Thus, pass GFP_ATOMIC to the libsas phy event notifier. Note, The now-replaced libsas APIs used in_interrupt() to implicitly decide which memory allocation type to use. This was only partially correct, as it fails to choose the correct GFP flags when just preemption or interrupts are disabled. Such buggy code paths are marked with "(@)" in the call chains above.

Pass GFP_ATOMIC to libsas port event notifier. Note, the now-replaced libsas APIs used in_interrupt() to implicitly decide which memory allocation type to use.

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.

For bisectability, a temporary _gfp() variant of such functions were added. All call sites then got converted use the _gfp() variants and explicitly pass GFP context.

For bisectability, a temporary _gfp() variant of such functions were added. All call sites then got converted use the _gfp() variants and explicitly pass GFP context. Having no callers left, the original libsas notifiers were then modified to accept gfp_t flags by default. Switch back to the original event notifiers API, while still passing GFP context. The _gfp() notifier variants will be removed afterwards. Signed-off-by: Ahmed S.
