Subject: [PATCH 0/3] kernfs: Convert from strlcpy() to strscpy()


One of the last users of strlcpy() is kernfs, which has some complex
calling hierarchies that needed to be carefully examined. This series
refactors the strlcpy() calls into strscpy() calls, and bubbles up all
changes in return value checking for callers.


Kees Cook (3):
  kernfs: Convert kernfs_walk_ns() from strlcpy() to strscpy()
  kernfs: Convert kernfs_name_locked() from strlcpy() to strscpy()
  kernfs: Convert kernfs_path_from_node_locked() from strlcpy() to
