Hi, We have been seeing some process crashes when performing hot remove of our virtual NVMeF target devices from the subsystem. Looking at the code for ns_remove - I saw a comment that states that there is no real quiesce of IO during subsystem pause, which seems to cause IO already in the system to attempt completions when the underlying device is no longer valid. Is there a plan to support this? Is there a design of how to quiesce the system without locking in the fast path? Shahar
