Based on 3.0-rc3 plus the 14 in June 5th "mm: tmpfs and trunc changes" plus the 7 in June 9th "tmpfs: simplify by splice instead of readpage", which were in preparation for it. I'm not sure who would really be interested in it: I'm Cc'ing this header mail as notification to a number of people who might care; but reluctant to spam you all with the 14+7+12 patches themselves, I hope you can pick them up from the list if you want (or ask me). What's it about? Extending tmpfs to MAX_LFS_FILESIZE by abandoning its peculiar swap vector, instead keeping a file's swap entries in the same radix tree as its struct page pointers: thus saving memory, and simplifying its code and locking. 1/12 radix_tree: exceptional entries and indices 2/12 mm: let swap use exceptional entries 3/12 tmpfs: demolish old swap vector support 4/12 tmpfs: miscellaneous trivial cleanups 5/12 tmpfs: copy truncate_inode_pages_range 6/12 tmpfs: convert shmem_truncate_range to radix-swap 7/12 tmpfs: convert shmem_unuse_inode to radix-swap 8/12 tmpfs: convert shmem_getpage_gfp to radix-swap 9/12 tmpfs: convert mem_cgroup shmem to radix-swap 10/12 tmpfs: convert shmem_writepage and enable swap 11/12 tmpfs: use kmemdup for short symlinks 12/12 mm: a few small updates for radix-swap fs/stack.c | 5 include/linux/memcontrol.h | 8 include/linux/radix-tree.h | 36 include/linux/shmem_fs.h | 17 include/linux/swapops.h | 23 init/main.c | 2 lib/radix-tree.c | 29 mm/filemap.c | 74 - mm/memcontrol.c | 66 - mm/mincore.c | 10 mm/shmem.c | 1515 +++++++++++------------------------ mm/swapfile.c | 20 mm/truncate.c | 8 13 files changed, 669 insertions(+), 1144 deletions(-) Hugh -- 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/
