Hi I have found that memory compaction (CONFIG_COMPACTION) is mainlined while looking at 2.6.35-rc5 source code. I have a question regarding its dependency on HUGETLB_PAGE. While trying to use CONFIG_COMPACTION on ARM architecture, I found that I cannot enable CONFIG_COMPACTION because it depends on CONFIG_HUGETLB_PAGE which is not available on ARM. I disabled the dependency and was able to build it. And it looks like working! My question is: why does it depend on CONFIG_HUGETLB_PAGE? Is it wrong to use it on ARM by disabling CONFIG_HUGETLB_PAGE?
