However, there are some architectures that do not support it, like m68k. So, make PAGE_OWNER also depend on having STACKTRACE_SUPPORT. This isn't ideal since it restricts the number of places PAGE_OWNER runs now, but it at least hits all the major architectures. tree: git://git.cmpxchg.org/linux-mmotm.git master head: 83b324c5ff5cca85bbeb2ba913d465f108afe472 commit: 2a561c9d47c295ed91984c2b916a4dd450ee0279 [484/499] debugging-keep-track-of-page-owners-fix config: make ARCH=m68k allmodconfig All warnings: warning: (PAGE_OWNER && STACK_TRACER && BLK_DEV_IO_TRACE && KMEMCHECK) selects STACKTRACE which has unmet direct dependencies (STACKTRACE_SUPPORT) Signed-off-by: Dave Hansen <dave@xxxxxxxxxxxxxxxxxx> Reported-by: Fengguang Wu <fengguang.wu@xxxxxxxxx> Signed-off-by: Andrew Morton <akpm@xxxxxxxxxxxxxxxxxxxx> --- lib/Kconfig.debug | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff -puN lib/Kconfig.debug~debugging-keep-track-of-page-owner-now-depends-on-stacktrace_support lib/Kconfig.debug --- a/lib/Kconfig.debug~debugging-keep-track-of-page-owner-now-depends-on-stacktrace_support +++ a/lib/Kconfig.debug @@ -101,7 +101,7 @@ config UNUSED_SYMBOLS config PAGE_OWNER bool "Track page owner" - depends on DEBUG_KERNEL + depends on DEBUG_KERNEL && STACKTRACE_SUPPORT select DEBUG_FS select STACKTRACE help _ Patches currently in -mm which might be from dave@xxxxxxxxxxxxxxxxxx are linux-next.patch mm-add-section_in_page_flags.patch mm-add-use-zone_end_pfn-and-zone_spans_pfn.patch mm-add-zone_is_empty-and-zone_is_initialized.patch mm-page_alloc-add-a-vm_bug-in-__free_one_page-if-the-zone-is-uninitialized.patch mmzone-add-pgdat_end_pfnis_empty-helpers-consolidate.patch mm-page_alloc-add-informative-debugging-message-in-page_outside_zone_boundaries.patch mm-page_alloc-add-informative-debugging-message-in-page_outside_zone_boundaries-fix.patch mm-add-helper-ensure_zone_is_initialized.patch mm-memory_hotplug-use-ensure_zone_is_initialized.patch mm-memory_hotplug-use-pgdat_end_pfn-instead-of-open-coding-the-same.patch drop_caches-add-some-documentation-and-info-messsge.patch debugging-keep-track-of-page-owners-fix.patch debugging-keep-track-of-page-owners-fix-2.patch debugging-keep-track-of-page-owners-fix-2-fix-fix.patch debugging-keep-track-of-page-owner-now-depends-on-stacktrace_support.patch -- To unsubscribe from this list: send the line "unsubscribe mm-commits" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
