  • allow converting fd into fhandle_t via AT_EMPTY_PATH
  • allow sysctl allowing unprivileged inode generation access to also allow getfhat.

These changes allow smbd process to convert an open fd into opaque file handle that is in process of being plumbed into our our Samba server to use as fast-path for looking up / opening files (helps in workloads that are constantly opening / closing files).
