Last patch is slightly off-topic, but it shares test results with previous patch. --- Konstantin Khlebnikov (4): shmem: simlify shmem_unlock_mapping shmem: tag swap entries in radix tree shmem: use radix-tree iterator in shmem_unuse_inode() mm: use swap readahead at swapoff include/linux/radix-tree.h | 1 lib/radix-tree.c | 93 -------------------------------------------- mm/shmem.c | 60 ++++++++++++++++++++-------- mm/swapfile.c | 3 - 4 files changed, 44 insertions(+), 113 deletions(-) -- Signature -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
