[PATCH 0/3] inotify.7, fanotify.7: fallocate triggers no event

[Heinrich Schuchardt]

the fanotify.7 and inotify.7 manpages do not describe whether fallocate.2 will
create events (FAN_MODIFY, IN_MODIFY).
Looking at fs/open.c no event seems to be created.
I ran a test program and could not detect any FAN_MODIFY event.
