[Lse-tech] [RFC][PATCH 2/7]: simple set of notifier_head definition changes
|
From: Chandra S. <sek...@us...> - 2005-11-19 02:20:04
|
Simple set of changes to files affected by the interface change in 1/7.
This patch updates the definitions and declarations of many of the
notifier chain heads. It also removes some repeated declarations in
include/linux/memory.h.
