   Not sure about that if it would happen on kernel-side: you need to
   
   1. have debug symbols on kernel to know what's happened
   2. be sure you're not on a VM and you have rights to create a SOS report
   
   I won't go in *both* the rabbit holes if possible :)
   The original code was making the assumption that any used `iocb` must be released at some point, but that's not what happen in a real world while using NFS (hard-mounted) and getting a timeout due to long kernel-side disk operation.
   I prefer, instead, logging that something bad has happened (error or warn level) and won't let the kernel crash silently, that's my 2 cents, but I'm opened to other opinions, bud :)
