Cover letter [PATCH 0/2] [SCSI] Don't overwhelm with messages when a device is unplugged
What follows are two patches.
The first I've been carrying for a long time. The second is recent.
We see over 2 million messages of sorts when a device(s) is unplugged right in the middle of heavy I/O.
"rejecting I/O to device being removed" and "rejecting I/O to dead device"...
These are printed so many times that they cause soft-lockup on all 4 CPUs in succession!...
The following patches remedy this sad situation.
