Hi Doug,
Do you perhaps have a proposal for how to do that without allocating a new
request from the error handler and without reserving a request for error
handling purposes.
Well yes. The SCSI ML could tell the block layer that the LU/device
was unavailable (temporarily) and then the ML would communicate
directly with the LLD. A block layer/mq bypass ...
Probably don't like that one. Why rule out reserving a request (e.g. one
per host)?
