kernfs_path*() functions always return the length of the full path but
the path content is undefined if the length is larger than the
provided buffer. This makes its behavior different from strlcpy() and
requires error handling in all its users even when they don't care
about truncation. In
kernfs_path*() functions always return the length of the full path but
the path content is undefined if the length is larger than the
provided buffer. This makes its behavior different from strlcpy() and
requires error handling in all its users even when they don't care
about truncation. In
