Hi Andrew, After merging the akpm-current tree, today's linux-next build (x86_64 allmodconfig) failed like this: In file included from include/linux/mm.h:318:0, from include/linux/highmem.h:7, from include/linux/bio.h:23, from include/linux/writeback.h:192, from include/linux/memcontrol.h:30, from include/linux/swap.h:8, from include/linux/suspend.h:4, from arch/x86/kernel/asm-offsets.c:12: include/linux/page-flags.h:371:26: error: macro "TESTPAGEFLAG" requires 3 arguments, but only 2 given TESTPAGEFLAG(Young, young) ^ include/linux/page-flags.h:372:25: error: macro "SETPAGEFLAG" requires 3 arguments, but only 2 given SETPAGEFLAG(Young, young) ^ include/linux/page-flags.h:371:1: error: unknown type name 'TESTPAGEFLAG' TESTPAGEFLAG(Young, young) ^ include/linux/page-flags.h:373:27: error: macro "TESTCLEARFLAG" requires 3 arguments, but only 2 given TESTCLEARFLAG(Young, young) ^ include/linux/page-flags.h:373:1: error: expected '=', ',', ';', 'asm' or '__attribute__' before 'TESTCLEARFLAG' TESTCLEARFLAG(Young, young) ^ include/linux/page-flags.h:374:20: error: macro "PAGEFLAG" requires 3 arguments, but only 2 given PAGEFLAG(Idle, idle) ^ include/linux/page-flags.h:373:1: error: unknown type name 'TESTCLEARFLAG' TESTCLEARFLAG(Young, young) ^ In file included from include/linux/highmem.h:7:0, from include/linux/bio.h:23, from include/linux/writeback.h:192, from include/linux/memcontrol.h:30, from include/linux/swap.h:8, from include/linux/suspend.h:4, from arch/x86/kernel/asm-offsets.c:12: include/linux/mm.h: In function '__compound_tail_refcounted': include/linux/mm.h:453:2: error: implicit declaration of function 'PageAnon' [-Werror=implicit-function-declaration] return PageAnon(page) && !PageSlab(page) && !PageHeadHuge(page); ^ Caused by commit 33c3fc71c8cf ("mm: introduce idle page tracking") from Linus' tree interacting with commit 3b1670dad702 ("page-flags: introduce page flags policies wrt compound pages") from the akpm-current tree (and presumably others). I have just dropped the akpm-current tree for today. I am sorry I rushed you to put out a cleaned up mmotm yesterday :-( -- Cheers, Stephen Rothwell sfr@xxxxxxxxxxxxxxxx -- To unsubscribe from this list: send the line "unsubscribe linux-next" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
