From 57f4c226d1e095a2db20c691c3cf089188fe1c5d Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Tue, 23 Mar 2010 15:32:53 +0900 Subject: [PATCH] x86: don't include slab.h from arch/x86/include/asm/pgtable_32.h Including slab.h from x86 pgtable_32.h creates a troublesome dependency chain w/ ftrace enabled. The following chain leads to inclusion of pgtable_32.h from define_trace.h. trace/define_trace.h trace/ftrace.h linux/ftrace_event.h linux/ring_buffer.h linux/mm.h asm/pgtable.h asm/pgtable_32.h slab.h itself defines trace hooks via linux/sl[aou]b_def.h linux/kmemtrace.h trace/events/kmem.h If slab.h is not included before define_trace.h is included, this leads to duplicate definitions of kmemtrace hooks or other include dependency problems. pgtable_32.h doesn't need slab.h to begin with. Don't include it from there. Signed-off-by: Tejun Heo Acked-by: Pekka Enberg Acked-by: Christoph Lameter Cc: Ingo Molnar Cc: Thomas Gleixner Cc: H.
