Changes since first patch: xfs_ag.h - moved pagb_list to before the #ifdef __KERNEL__ xfs_alloc.h - moved xfs_alloc_xxx_busy to the first (and now only)
#ifdef __KERNEL__ blockxfs_bmap.h - moved xfs_bmap_finish to the start of the __KERNEL__
block.xfs_inode.h - had to use struct xfs_inode instead of xfs_inode_t for
shared function prototypes (and unified kernel only
code into one block).xfs_inode_item.h - move xfs_ilog_xxx functions before __KERNEL__
block.xfs_mount.h - clarified #ifndef __KERNEL__/#else at start. xfs_trans.h - unified kernel structures, constants, flags and function
