Subject: [PATCH v2 0/2] Avoid obvious double update_rq_clock warning

These two patches are about the kernel scheduler:

patch 1: fixed the issue that kernel may trigger WARN_DOUBLE_CLOCK warning.
patch 2: removed some no longer needed comments in the deadline scheduler
and cleaned up the code.

v2:
   - Added double_rq_clock_clear_update inline helper to clear RQCF_UPDATED
     of rq->clock_update_flags.
   - split into two separate patches.
