While we are at introducing and moving around code, i've done a big
cleanup of all code touched/introduced by your patchset. The
gtod-B11-cleanup.tar.gz file containing the cleanup patch-series can be
found at:
http://redhat.com/~mingo/gtod-patches/
(i'll send the patches individually as well, as replies to your mails).
one side-effect of the cleanups is that the core Linux NTP code has now
become quite readable, for the first time in history ;-)
the cleanups are also included in the 2.6.14-rt18 tree, and i've tested
them on a UP and on an SMP box. The cleanups are 99% coding style
related, but while reviewing the code i've also inserted a few TODO
entries:
+ /* TODO: bogus limit of 4 CPUs? --mingo */
+/* TODO: why a seqlock? It's only write-locked, so should be a spinlock. */
+ /* TODO: is 2*time_constant correct? --mingo */
+ * TODO: shouldnt we write-lock xtime_lock below, and then
+ * TODO: shouldnt txc->time be filled in here, within ntp_lock and
