No one cares that this has no multipathing capabilities what-so-ever? despite being issued on the mpath device node? I know we are not doing multipathing for userspace today, but this feels like an alternative I/O interface for nvme, seems a bit cripled with zero multipathing capabilities...

Got it, thanks. Passthrough (sync or async) just returns the failure to user-space if that fails. No attempt to retry/requeue as the block path does.
I know, and that was my original question, no one cares that this interface completely lacks this capability? Maybe it is fine, but it is not a trivial assumption given that this is designed to be more than an interface to send admin/vs commands to the controller...
