How much of a real issue is this?
block io_timeout defaults to 30 seconds which are considered a universal eternity for pretty much any nvme fabric. Moreover, io_timeout is mutable already on a per-namespace level.
This leaves the admin_timeout which goes beyond this to 60 seconds...
Can you describe what exactly are you trying to solve?
