Subject: [PATCH 2/2] file capabilities: turn on by default


Now that file capabilities can be turned off at boot, go ahead
and compile them into the kernel by default by making
CONFIG_SECURITY_FILE_CAPABILITIES=y the default.

Note that the boot flag no_file_caps must be specified to turn
file capabilities off, as by default they are on.  So the
default behavior is in fact changed.
