This is an updated patchset rebasing onto -torvalds master (post
6.11-rc1), and addressing comments from Michal and Tejun.
As requested by Tejun and Johannes, I've removed the explicit check for
the string "reset", so it now allows any non-empty string. (Empty
strings get filtered before our write handler executes)
I've also made several of the field reads and writes atomic with
{READ,WRITE}_ONCE, and adjusted more of the types to be unsigned.
