I just see that on the kernel before v2.6.39, the "defrag" interface is "[yes] no" or "yes [no]"(eg. RHEL6). While it's changed to boolean after commit e27e6151b154 in v2.6.39-rc4. So, you should deal with the multi-style interface of this "defrag", + SAFE_FILE_SCANF(cleanup, PATH_KHPD "defrag", "%ld", &defrag); Thanks, Wanlong Gao > > Wanlong, I included you into 'Tested-by' thread, thanks for > your reviewing and testing the patchset. > > Zhouping Liu (3): > mm/thp: new case thp04.c > lib/mem: introduce a new function set_global_mempolicy() > mm/thp: add new case thp05 > > runtest/mm | 6 ++ > testcases/kernel/mem/include/mem.h | 12 +++ > testcases/kernel/mem/lib/mem.c | 203 > ++++++++++++++++++++++++++++++++++++- > testcases/kernel/mem/thp/thp04.c | 136 +++++++++++++++++++++++++ > testcases/kernel/mem/thp/thp05.c | 152 +++++++++++++++++++++++++++ > 5 files changed, 508 insertions(+), 1 deletion(-) > create mode 100644 testcases/kernel/mem/thp/thp04.c > create mode 100644 testcases/kernel/mem/thp/thp05.c > ------------------------------------------------------------------------------ Precog is a next-generation analytics platform capable of advanced analytics on semi-structured data.
