Cover letter [PATCH 0/4] sched: Display deadline bandwidth and other SCHED_DEBUG clean up
[ Nothing different since my v2 I posted, except hopefully people
will look at it this time :-) I also removed the RFC ]
I'm starting to play with SCHED_DEADLINE a bit and I'm able to cause a bandwidth "leak". Then I realized there's no way to examine what bandwidths are enabled on which CPUs. I added the bandwith ratios to the /proc/sched_debug file.
I will be posting the SCHED_DEADLINE issue in a separate thread.

Before adding this code, I also realized there was a bit of SCHED_DEBUG code in the kernel/sched/core.c file, and decided to move that to kernel/sched/debug.c to clean the core.c file up a bit. Those patches are mostly orthognal to the deadline_bw file, but decided to group them together here.
Steven Rostedt (Red Hat) (4):
sched: Move sched_feature file setup into debug.c
sched: Move sched_domain_sysctl to debug.c
sched: Add bandwidth ratio to /proc/sched_debug
tracing: Add __print_ns_to_secs() and __print_ns_without_secs() helpers
