Cover letter [PATCH v3 0/3] kernfs: Convert from strlcpy() to strscpy()
Hi,
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. Future work in kernfs and sysfs will see the replacement of open-coded string handling with the seq_buf API, but we need to do one thing at a time.
Thanks!
