sysfs: Fix locking and factor out sysfs_sd_setattr
Cleanly separate the work that is specific to setting the attributes of a sysfs_dirent from what is needed to update the attributes of a vfs inode. Additionally grab the sysfs_mutex to keep any nasties from surprising us when updating the sysfs_dirent. Acked-by: Tejun Heo <tj@kernel.org> Signed-off-by: Eric W.
