SubjectPOSIX timers for 2.4.0-test7
Date
Hi Linus,

I have updated the POSIX timer patches to work with 2.4.0-test7.
Please consider this patch.
See also http://www.rhdv.cistron.nl/posix.html for more information and
http://www.rhdv.cistron.nl/2.4.0-test7.timer.patch or the attachment for the
patch.

Robert
