For v3, we've addressed the problem with unwritten extents that Dave Chinner pointed out. Rather than testing bh_unwritten() as he suggested, I opted for checking !buffer_mapped() as block_read_full_page() in fs/buffer.c does. While I'm in that function I renamed the buffer_head from 'tmp' to 'bh' to follow normal usage. I also folded the "ext4: Add xip hole punching" patch into the main "Add XIP functionality" patch since otherwise we're introducing broken functionality in the middle of the series.
