Add a simple cleanup helper so we can cleanup struct path easily. No need for any extra machinery. Avoid DEFINE_FREE() as it causes a local copy of struct path to be used. Just rely on path_put() directly called from a cleanup helper. Signed-off-by: Christian Brauner <brauner@kernel.org> --- include/linux/path.h | 9 +++++++++ 1 file changed, 9 insertions(+)
