sendfile: allows bypassing of notifier events

do_sendfile() in fs/read_write.c does not call the fsnotify functions,
unlike its neighbors.  This manifests as a lack of inotify ACCESS events
when a file is sent using sendfile(2).

[akpm@linux-foundation.org: use fsnotify_modify(out.file), not fsnotify_access(), per Dave]
