From 41fc1c27452e041a18e5141b8203ee0ea72bc483 Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Thu, 2 Aug 2007 21:38:03 +0900 Subject: sysfs: make sysfs_add/remove_one() call link/unlink_sibling() implictly When adding or removing a sysfs_dirent, the user used to be required to call link/unlink separately. It was for two reasons - code looked like that before sysfs_addrm_cxt conversion and to avoid looping through parent_sd->children list twice during removal. Performance optimization during removal just isn't worth it. Make sysfs_add/remove_one() call sysfs_link/unlink_sibing() implicitly. This makes code simpler albeit slightly less efficient. This change doesn't introduce any noticeable behavior change.
