Subject: [PATCH 1/1] Enable fanotify API by default.

From: Heinrich Schuchardt <xypron.glpk@....de>

The fanotify interface is the basis for on access malware detection
in the Linux kernel. The development of a prior solution (DazukoFS)
has been stopped therefore.

Both free (ClamAV) as well as commercial viurs scanners (Sophos
Anti-Virus, AVG) using this interface exist.

Since kernel version 3.8.0 the implementationof the fanotify inter-
face is errorfree enough to be used on a productive system.
Personally I have been using it for virus scanning on multiple
systems for several months without issues while a developing a
wrapper around ClamAV, see
https://github.com/xypron/skyldav

A large scale usage of the fanotify interface can only expected if
the API is enabled by default.

Hence I recommend to change the Kconfig file accordingly.
