	- minor change to keep files the same/similar between 2.4 and 2.5.

	- Use a LINVFS_GET_VPTR macro (in 2.5 is the same as LINVFS_GET_VP,
	  but is different in 2.4) to allow us to keep a whole bunch of code
	  the same between the two trees.

linux/fs/xfs/pagebuf/page_buf.h - 1.19
	- structures moved recently, move their associated comments with them.
