Subject: [PATCH 0/4] SCHED_DEADLINE fixes and cleanups 

Hi,

here are some fixes, cleanups and improvements for SCHED_DEADLINE.

Patch 0001 just removes a duplicate declaration from sched/sched.h.

Patch 0002 fixes a bug I introduced some time ago, when removing
the dl_new field from sched_dl_entity in
72f9f3fdc928dc3ecd223e801b32d930b662b6ed.
This is the same patch I already sent some time ago, because at the
end of the discussion it was not clear to me if some changes are needed
or not.

Patch 0003 renames the confusing __dl_clear() function, as suggested
by Peter (actually, this is Peter's patch... I hope I did the SoB thing
correctly)

Patch 0004 saves reduces the size of sched_dl_entity by using bitfields
instead of whole integers for boolean values.

Peter Zijlstra (1):
  sched/deadline: rename __dl_clear() to __dl_sub()

luca abeni (3):
  sched/sched.h: remove duplicate prototype of __dl_clear_params()
  sched/deadline: fix switching to -deadline
  sched/deadline: use C bitfields for the state flags
