This # worker thread starts touching the device which see a device error # (EEH) and hence queues up an event in the powerpc EEH worker # thread. nvme_reset_work() then continues and runs # nvme_remove_dead_ctrl_work() which results in unbinding the driver # from the device and hence releases all resources. At the same time, # the EEH worker thread starts doing the EEH .error_detected() driver # callback, which no longer works since the resources have been freed. # # This fixes the problem in the same way the generic PCIe AER code (in # drivers/pci/pcie/aer/aerdrv_core.c) does. It makes the EEH code hold # the device_lock() while performing the driver EEH callbacks and # associated code. This ensures either the callbacks are no longer # register, or if they are registered the driver will not be removed # from underneath us. # # This has been broken forever. The EEH call backs were first introduced # in 2005 (in 77bd7415610) but it's not clear if a lock was needed back # then. # # Fixes: 77bd74156101 ("[PATCH] powerpc: PCI Error Recovery: PPC64 core recovery routines") #
