There is the unit attention. camcontrol(8) has a default
retry_count of 1, in case someone sets the -E flag without
setting -C.
The CAM_PASS_ERR_RECOVER behavior was only broken with the
CAMIOCOMMAND ioctl, which is the synchronous pass(4) API. It has
worked as intended (error recovery is only done when the flag
is set) in the asynchronous API (CAMIOQUEUE ioctl).
sys/cam/scsi/scsi_pass.c:
In passsendccb(), when calling cam_periph_runccb(), only
specify the error routine when CAM_PASS_ERR_RECOVER is set.
share/man/man4/pass.4:
Document that CAM_PASS_ERR_RECOVER is needed to enable
error recovery.

Fix handling of a NFSv4.1 callback reply from the session cache.
The nfsv4_seqsession() call returns NFSERR_REPLYFROMCACHE when it has a
reply in the session, due to a requestor retry. The code erroneously
assumed a return of 0 for this case. This patch fixes this and adds
a KASSERT(). This would be an extremely rare occurrence. It was found
during code inspection during the pNFS server development.
