From: Eric W. Biederman Date: Tue, 30 Mar 2010 18:31:29 +0000 (-0700) Subject: driver core: Implement ns directory support for device classes. X-Git-Tag: v2.6.35-rc1~459^2~14 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=f349cf34731c3b3eddbcd63cb04489aee2c405bd;p=platform%2Fkernel%2Flinux-stable.git driver core: Implement ns directory support for device classes. device_del and device_rename were modified to use sysfs_delete_link and sysfs_rename_link respectively to ensure when these operations happen on devices whose classes are in namespace directories they work properly.
