[RFC][PATCH v2 09/34] do_last(): collapse the call of path_to_nameidata()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Al Viro <viro@xxxxxxxxxxxxxxxxxx>

... and shift filling struct path to just before the call of
handle_mounts().  All callers of handle_mounts() are
immediately preceded by path->mnt = nd->path.mnt now.
