commit 8893cf6c upstream. Commit 669f0441 ("scsi: srp_transport: Move queuecommand() wait code to SCSI core") can make scsi_internal_device_block() sleep. However, the mpt3sas driver can call this function from an interrupt handler. Hence add a second argument to scsi_internal_device_block() that restores the old behavior of this function for the mpt3sas handler. The call chain that triggered an "IRQ handler enabled interrupts" complaint is as follows: _base_interrupt() -> _base_async_event() -> mpt3sas_scsih_event_callback() -> _scsih_check_topo_delete_events() -> _scsih_block_io_to_children_attached_directly() -> _scsih_block_io_device() -> _scsih_internal_device_block() -> scsi_internal_device_block() Reported-by: Omar Sandoval <osandov@osandov.com> Signed-off-by: Bart Van Assche <bart.vanassche@sandisk.com> Cc: Omar Sandoval <osandov@osandov.com> Cc: Hannes Reinecke <hare@suse.com> Cc: Sagi Grimberg <sagi@grimberg.me> Cc: Christoph Hellwig <hch@lst.de> Cc: Sathya Prakash <sathya.prakash@broadcom.com> Cc: Chaitra P B <chaitra.basappa@broadcom.com> Cc: Suganath Prabu Subramani <suganath-prabu.subramani@broadcom.com> Cc: Sreekanth Reddy <Sreekanth.Reddy@broadcom.com> Tested-by: Omar Sandoval <osandov@fb.com> Signed-off-by: Martin K.
