Christian Brauner eee3a0e939 fanotify: use pidfd_prepare() ... We generally try to avoid installing a file descriptor into the caller's file descriptor table just to close it again via close_fd() in case an error occurs. Instead we reserve a file descriptor but don't install it into the caller's file descriptor table yet. If we fail for other, unrelated reasons we can just close the reserved file descriptor and if we make it past all meaningful error paths we just install it. Fanotify gets this right already for one fd type but not for pidfds. Use the new pidfd_prepare() helper to reserve a pidfd and a pidfd file and switch to the more common fd allocation and installation pattern.
