litmus2008.git/kernel, branch master [ARCHIVE] Old LITMUS^RT 2008 version (for reference). rt domain: evil hack to avoid recursive hrtimer lock acquisition 2009-05-04T05:17:08+00:00 Bjoern B. Brandenburg bbb@cs.unc.edu 2009-05-04T05:17:08+00:00 5b0c2aac1d78f1db36c85bd5cd1e215c7cbd2dd6 This is a really dirty hack, but works for now since our real-time tasks do not use hrtimer_wakeup(). The need for this will go away when we port since newer versions of the Linux kernel allow timers to be activated directly in the scheduler.

This depends on the ability to send the special 'pull_timers' IPI
even with IRQs disabled.

Other quantum-based plugins also require the present flag. Hence,
move it to the core data structure

implementation based on Feather-Trace and ftdev.
