From: Eric W. Biederman Date: Mon, 20 Aug 2007 12:36:30 +0000 (+0900) Subject: sysfs: Make sysfs_mount static X-Git-Tag: v2.6.24-rc1~1394^2~33 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=7d0c7d676cc066413e1583b5af9fba8011972d41;p=pandora-kernel.git sysfs: Make sysfs_mount static This patch modifies the users of sysfs_mount to use sysfs_root instead (which is what they are looking for). It then makes sysfs_mount static to keep people from using it by accident. The net result is slightly faster and cleaner code. Signed-off-by: Eric W.
