From a68c2f12b4b28994aaf622bbe5724b7258cc2fcf Mon Sep 17 00:00:00 2001 From: Scott Wolchok Date: Thu, 20 Dec 2012 15:05:52 -0800 Subject: 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).
