Luis, > Since commit 80c49563e250 ("scsi: scsi_debug: implement IMMED bit") > there are long delays in F_SYNC_DELAY and F_SSU_DELAY. This can cause > a memory leak in schedule_resp(), which can be invoked while unloading > the scsi_debug module: free_all_queued() had already freed all sd_dp > and schedule_resp will alloc a new one, which will never get freed. > Here's the kmemleak report while running xfstests generic/350: Applied to 4.18/scsi-fixes.
