Subject: configfs+dlm: Separate out __CONFIGFS_ATTR into configfs.h
From: Satyam Sharma <ssatyam@xxxxxxxxxxxxxx>
fs/dlm/config.c contains a useful generic macro called __CONFIGFS_ATTR that is
similar to sysfs' __ATTR macro that makes defining attributes easy for any
user of configfs. Separate it out into configfs.h so that other users
(forthcoming in dynamic netconsole patchset) can use it too.
