Tejun Heo d0ae3d4347 kernfs: add REMOVED check to create and rename paths ... kernfs currently assumes that the caller doesn't try to create a new node under a removed parent, rename a removed node, or move a node under a removed node. While this works fine for sysfs, it'd be nice to have protection against such cases especially given that kernfs is planned to add support for mkdir, rmdir and rename requsts from userland which may make race conditions more likely. This patch updates create and rename paths to check REMOVED and fail the operation with -ENOENT if performed on or towards removed nodes. Note that remove path already has such check.
