These are two patches that address two major issues with that series. The first patch is almost certainly unrelated to what he saw due to fact his vmstats showed no huge page activity but the fix is important. The second patch restores performance of one benchmark to similar levels to 3.19-vanilla but it still has to be tested on his workload. While I have a test configuration for his workload, I don't have either the KVM setup or suitable storage to test against. It also needs to be reviewed and tested on ppc64. arch/powerpc/include/asm/pgtable-ppc64.h | 16 ++++++++++++++++ arch/x86/include/asm/pgtable.h | 14 ++++++++++++++ include/asm-generic/pgtable.h | 19 +++++++++++++++++++ mm/huge_memory.c | 23 ++++++++++++++++++----- mm/mprotect.c | 5 +++++ 5 files changed, 72 insertions(+), 5 deletions(-) -- 2.1.2 _______________________________________________ xfs mailing list xfs@oss.sgi.com http://oss.sgi.com/mailman/listinfo/xfs
