The provides them and the comments in the file indicate that it is supposed to be used by user-level code. But the file is not installed. The patch below installs the headers and marks the unstable flags as out-of-bounds. The page-type tool is also adjusted to not duplicate the definitions Signed-off-by: Ulrich Drepper include/linux/Kbuild | 1 + include/linux/kernel-page-flags.h | 4 ++++ tools/vm/page-types.c | 28 +--------------------------- 3 files changed, 6 insertions(+), 27 deletions(-) diff --git a/include/linux/Kbuild b/include/linux/Kbuild index 3c9b616..50f55c7 100644 --- a/include/linux/Kbuild +++ b/include/linux/Kbuild @@ -227,6 +227,7 @@ header-y += kdev_t.h header-y += kernel.h header-y += kernelcapi.h +header-y += kernel-page-flags.h header-y += keyboard.h header-y += keyctl.h header-y += l2tp.h diff --git a/include/linux/kernel-page-flags.h b/include/linux/kernel-page-flags.h index 26a6571..a1bdf69 100644 --- a/include/linux/kernel-page-flags.h +++ b/include/linux/kernel-page-flags.h @@ -32,6 +32,8 @@ #define KPF_KSM 21 #define KPF_THP 22 +#ifdef __KERNEL__ + /* kernel hacking assistances * WARNING: subject to change, never rely on them! */ @@ -44,4 +46,6 @@ #define KPF_ARCH 38 #define KPF_UNCACHED 39 +#endif /* __KERNEL__ */ + #endif /* LINUX_KERNEL_PAGE_FLAGS_H */ diff --git a/tools/vm/page-types.c b/tools/vm/page-types.c index 7dab7b25..f77c96b 100644 --- a/tools/vm/page-types.c +++ b/tools/vm/page-types.c @@ -35,6 +35,7 @@ #include #include #include "../../include/linux/magic.h" +#include "../../include/linux/kernel-page-flags.h" #ifndef MAX_PATH @@ -73,33 +74,6 @@ #define KPF_BYTES 8 #define PROC_KPAGEFLAGS "/proc/kpageflags" -/* copied from kpageflags_read() */ -#define KPF_LOCKED 0 -#define KPF_ERROR 1 -#define KPF_REFERENCED 2 -#define KPF_UPTODATE 3 -#define KPF_DIRTY 4 -#define KPF_LRU 5 -#define KPF_ACTIVE 6 -#define KPF_SLAB 7 -#define KPF_WRITEBACK 8 -#define KPF_RECLAIM 9 -#define KPF_BUDDY 10 - -/* [11-20] new additions in 2.6.31 */ -#define KPF_MMAP 11 -#define KPF_ANON 12 -#define KPF_SWAPCACHE 13 -#define KPF_SWAPBACKED 14 -#define KPF_COMPOUND_HEAD 15 -#define KPF_COMPOUND_TAIL 16 -#define KPF_HUGE 17 -#define KPF_UNEVICTABLE 18 -#define KPF_HWPOISON 19 -#define KPF_NOPAGE 20 -#define KPF_KSM 21 -#define KPF_THP 22 - /* [32-] kernel hacking assistances */ #define KPF_RESERVED 32 #define KPF_MLOCKED 33 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
