fanotify: WARN_ON against too large file handles

Browse source

[ Upstream commit 572c28f27a ]

struct fanotify_error_event, at least, is preallocated and isn't able to
to handle arbitrarily large file handles.  Future-proof the code by
complaining loudly if a handle larger than MAX_HANDLE_SZ is ever found.
