ext4: Add WARN_ON on unmapped dirty buffer_heads in writepage
fs: Don't clear dirty bits in block_write_full_page()
vfs: Unmap underlying metadata of new data buffers only when buffer is m
ext4: Make sure blocks are properly allocated under mmaped page even whe
vfs: Add better VFS support for page_mkwrite when blocksize < pagesize

FYI, I've added the following to the unstable portion of the patch
queue, and have started running tests (fsx, fsstress, and dbench)
using 1k blocksizes, using a variety of ext4 mount options. So far,
things look good.

How goes the reviews/comments? Are we planning on pushing this to
Linus at the beginning of the next merge window?
