kernfs node can be created in two separate steps - allocation and activation. This is used to make kernfs nodes visible only after the internal states attached to the node are fully initialized. kernfs_find_and_get_node_by_id() currently allows lookups of nodes which aren't activated yet and thus can expose nodes are which are still being prepped by kernfs users. Fix it by disallowing lookups of nodes which aren't activated yet. kernfs_find_and_get_node_by_ino() Signed-off-by: Tejun Heo <tj@kernel.org> Reviewed-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> Cc: Namhyung Kim <namhyung@kernel.org> |

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
