I'm not sure it's possible to avoid such a race without introducing

below, and invoking scsi_block_eh() and scsi_unblock_eh() around any
reconnect activity not initiated from the SCSI EH thread ?
[PATCH] Add scsi_block_eh() and scsi_unblock_eh()
Hi Bart,
The description doesn't match the code at all, do you mean try to
serialize the reconnect activity with this new block_eh_mutex?
In case it wasn't clear, the actual scsi_block_eh() and
scsi_unblock_eh() calls aren't present in the patch I posted, only their
implementation.
P.S.: please fix your e-mail client such that it does not break e-mail
threading. There are no "In-Reply-To:" tags in the header of your e-mails.
Thanks,
Bart.
