[PATCH 1/1] Fanotify: make default values visible

[xypron . glpk]

From: Heinrich Schuchardt <xypron.glpk@xxxxxx>

The fanotify API imposes limits on
  number of queue entries
  number of queues
  number of listeners.

Opaque limits lead to unnecessary redefinitions in user coding.
Limits should therefore be visible in includes or should be removed.

Signed-off-by: Heinrich Schuchardt <xypron.glpk@xxxxxx>
