6.6-stable review patch. If anyone has any objections, please let me know.
------------------
From: "Steven Rostedt (Google)" <rostedt@xxxxxxxxxxx>
This reverts commit fa18a8a0539b02cc621938091691f0b73f0b1288.
The eventfs was not designed properly and may have some hidden bugs in it.
Linus rewrote it properly and I trust his version more than this one. Revert
the backported patches for 6.6 and re-apply all the changes to make it
equivalent to Linus's version.
