  "message": "ext4: Use slab allocator for sub-page sized allocations\n\nNow that the SLUB seems to be fixed so that it respects the requested\nalignment, use kmem_cache_alloc() to allocator if the block size of\nthe buffer heads to be allocated is less than the page size.\nPreviously, we were using 16k page on a Power system for each buffer,\neven when the file system was using 1k or 4k block size.\n\nSigned-off-by: \"Theodore Ts\u0027o\" \u003ctytso@mit.edu\u003e\n\n\n",
