It also fixes potential memory corruption when swapping out hugepage backed kvm (host_level wasn't read inside the mmu notifier protected critical section of the page fault). It cleanups some bits in khugepaged and notably it's removing transparent_hugepage/khugepaged/enabled. Now khugepaged is started automatically if transparent_hugepage/enabled is set to "always|madvise" and it exits if it's set to "never" (I found it too confusing to have it separated and an unnecessary annoyance having to change two files instead of just one). I removed the dependency on embedded to set transparent hugepage support to N at compile time, and I leave the default to N to reduce as much as possible the risk while merging the feature. All reports I have says it's very stable (the only two open issues in migrate vs execve and in the kvm patch should be fixed in #22). There is no easy way this can work with the new anon-vma code until I adapt it significantly (as an example see how wait_split_huge_page is implemented right now http://git.kernel.org/?p=linux/kernel/git/andrea/aa.git;a=blob_plain;f=include/linux/huge_mm.h;hb=HEAD), and I'll have to consider if it's possible to move completely away from the anon-vma lock and use compound_lock or something else. For now this has to run on the old stable anon-vma code to be stable. I added more details to the generic document. http://git.kernel.org/?p=linux/kernel/git/andrea/aa.git;a=blob_plain;f=Documentation/vm/transhuge.txt;hb=HEAD If anybody wants a patchbomb let me know. -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxxx For more info on Linux MM, see: http://www.linux-mm.org/ .
