I wonder how it performs against an NFS server with lots of files, especially one over a kinda-crappy connection. Putting an unreliable network service behind blocking POSIX syscalls is one of the main reasons NFS is a terrible design choice (as can be seen by anyone who's tried to ctrl+c any app that's reading from a broken NFS folder), but I wonder if io_uring mitigates the bad parts somewhat.

Theoretically "intr" mounts allowed signals to interrupt operations waiting on a hung remote server, but Linux removed the option long ago[1] (FreeBSD still supports it)[2]. "soft" might be the only workaround on Linux.
