Hidetoshi Seto (4): Lock the new THP when collapsing pages Free the collapsed pages after the new THP is mapped. Check whether pages are poisoned before copying Check whether the new THP is poisoned before it is mapped to APL. mm/huge_memory.c | 75 ++++++++++++++++++++++++++++++++++++++++++++++------- 1 files changed, 65 insertions(+), 10 deletions(-) -- 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/
