[PATCHSET,next,0/6] Move eventfd cq tracking into io_ev_fd

Hi,

For some reason this ended up being a series of 6 patches, when the
goal was really just to move evfd_last_cq_tail out of io_ring_ctx
and into struct io_ev_fd, where it belongs. But this slowly builds to
that goal, and the final patch does the move unceremoniously.

Patches are on top of current -git with for-6.12/io_uring pulled in.
