This reverts commit d8f492a059728bbd397defbc9b8d2f4159d869b5.
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.
