Hello.

Let's suppose that we have ordinal block file system:

writepage(struct page *page, struct writeback_control *wbc)
{
    return block_write_full_page(page, get_block, wbc);
}

Who have to full newly allocated block with zeros?

Am I right if make it in get_block using sb_* functions,
it may cause many troubles because of "inode cache" and block device cache
is seperate things?
