I'm planning on doing 2.4.37.12 once I'm finished with 2.6.27.60. However I'll
have to find another place to host it, as the 2.4 tree was never completely
recovered from master.kernel.org after the break-in, and admins there have
many more important things to do than to spend their time restoring the 2.4
files. Probably that I'll put that into my account.

BTW, since you're asking, you seem to still be using 2.4. Do you think it's
worth pursuing maintenance over 2.4.37.12 and if so for how long ? I'm asking
because until the break-in, I felt like almost nobody was using it anymore,
but since the break-in, I received a number of mails asking where to download
it. So now I assume that there are still users, but they're too much silent.

Regards,
Willy
