Hello Bart Van Assche, The patch f93ed747e2c7: "scsi: core: Release SCSI devices synchronously" from Oct 14, 2022, leads to the following three Smatch static checker warnings: 1) drivers/scsi/bfa/bfad_bsg.c:2551 bfad_iocmd_lunmask_reset_lunscan_mode() warn: sleeping in atomic context bfad_iocmd_lunmask() <- disables preempt -> bfad_iocmd_lunmask_reset_lunscan_mode() -> scsi_device_put() (This is inside the calls to bfad_reset_sdev_bflags() macro). 2) drivers/scsi/device_handler/scsi_dh_alua.c:853 alua_rtpg_select_sdev() warn: sleeping in atomic context alua_rtpg_work() <- disables preempt -> alua_rtpg_select_sdev() -> scsi_device_put() 3) drivers/scsi/device_handler/scsi_dh_alua.c:1013 alua_rtpg_queue() warn: sleeping in atomic context alua_check_vpd() <- disables preempt -> alua_rtpg_queue() -> scsi_device_put() Hopefully, this bug report is straight forward. The fixes are probably complicated though. :P Basically the function marked "disables preempt" takes a spin lock and calls the other function which calls scsi_device_put(). regards, dan carpenter
