Drivers: scsi: storvsc: Implement a eh_timed_out handler

Browse source

commit 56b26e69c8 upstream.

On Azure, we have seen instances of unbounded I/O latencies. To deal with
this issue, implement handler that can reset the timeout. Note that the
host gaurantees that it will respond to each command that has been issued.
