From b4277d3dd5a7400c1ea7fd4e7d64bda8899f84f5 Mon Sep 17 00:00:00 2001 From: Eric Paris Date: Thu, 17 Dec 2009 20:12:06 -0500 Subject: [PATCH] fsnotify: use fsnotify_create_event to allocate the q_overflow event Currently fsnotify defines a static fsnotify event which is sent when a group overflows its allotted queue length. This patch just allocates that event from the event cache rather than defining it statically. There is no known reason that the current implementation is wrong, but this makes sure the event is initialized and created like any other.
