sched: x86: allow single-depth wchan output sched.o gets smaller and faster if we compile it with -fomit-frame-pointers, so make this a config option. The cost is the loss of multi-depth wchan lookups - but SysRq-T is a sufficient replacement for them anyway, so their utility is much lower these days. the size difference is significant: text data bss dec hex filename 34005 3462 24 37491 9273 sched.o.before 33470 3462 24 36956 905c sched.o.after Signed-off-by: Ingo Molnar <[EMAIL PROTECTED]> Signed-off-by: Peter Zijlstra <[EMAIL PROTECTED]> Signed-off-by: Mike Galbraith <[EMAIL PROTECTED]> Reviewed-by: Thomas Gleixner <[EMAIL PROTECTED]> --- arch/i386/Kconfig | 11 +++++++++++ 1 files changed, 11 insertions(+), 0 deletions(-) diff --git a/arch/i386/Kconfig b/arch/i386/Kconfig index f1486f8..bf9aafa 100644 --- a/arch/i386/Kconfig +++ b/arch/i386/Kconfig @@ -214,6 +214,17 @@ config X86_ES7000 endchoice +config SCHED_NO_NO_OMIT_FRAME_POINTER + bool "Single-depth WCHAN output" + default y + help + Calculate simpler /proc/<PID>/wchan values.
