ChangeSet 1.1722.111.25, 2004/06/11 17:22:53-07:00, linux@kodeaffe.de [PATCH] sysfs: fs/sysfs/inode.c: modify parents ctime and mtime on creation When a node is added to sysfs (e.g. a device plugged in via USB), the filesystem fails to make this change visible in the parent directory's ctime/mtime. This is in contrast to removing a device, because in that case, sysfs makes use of the function simple_unlink from fs/libfs.c which takes care of that. Instead of using simple_link from fs/libfs.c on creation, sysfs implements its own mechanism. This patch hooks into the function sysfs_create and sets the ctime and the mtime of the parent to CURRENT_TIME.
