And what about e.g. sd_check_events() or sr_check_events() ? Maybe I should explain why I started looking at the SCSI error handler in so much detail. While running disk removal tests against ib_srp I found out that the SCSI error handler thread can invoke the LLD's abort and reset handlers long after scsi_remove_host() finished. That's why I came up with this patch: "[PATCH 05/15] ib_srp: Avoid that SCSI error handling triggers a crash" (http://www.mail-archive.com/linux-rdma@xxxxxxxxxxxxxxx/msg11234.html). But I'm still wondering whether that's the right approach. Should this issue be addressed in each LLD or in the SCSI core ?
