The last two releases hadn't reached end-of-life yet. I just updated
that entry, with the latest numbers for F7/F8, and threw in F9 too.

      total    kernel
F7    5534     724
F8    7589     902
F9    4624     292

Given F9 has only been out a few weeks, that's quite high.  As more
people move from F7 -> F8 as F7 gets closer to end of life, the bug
count there is shifting too.
(for point of reference, F7 is on 2.6.24, F8 is about to get a .25 update,
 F9 was released with .25)

My majority of my job is still spending reading and dealing with bugzilla.
I think if there were a noticable drop-off, I'd have more time to be
sitting around eating cheetos or doing something else.  That hasn't happened.
