Re: [PATCH 3/3] AFS: Implement basic file write support

set_page_dirty() will set I_DIRTY_PAGES only.  ie: the inode has dirty
pagecache data.

To tell the VFS that the inode itself is dirty one needs to run
mark_inode_dirty().

But what's the difference in this case?  I don't need to write the inode back
per se, and the inode attributes can be updated by the mechanism of data
storage.
