Oh boy, linux NFS bugs! this was supposed to be fixed in 2.x, but here I am, in kernel 6.1, same issue! `nfsiod` hangs, can't SIGKILL/SIGSEGV/SIGXCPU as root, `/proc/$pid/maps` is empty, strace/gdb are denied while running as root for only this process, `/proc/$pid/stack` only shows a single kthread that's stuck waiting for a fork to return, and... what the hell is `rescuer_thread`? apparently, deprecated in kernel 3.10, whatever the hell it is... wait, how did this even make a call without memory?

it's gonna be one of those days, isn't it?
