[PATCH 00/11] remove xfs_iomap

[Christoph Hellwig]

This series gets rid of the xfs_iomap structure which we use to
communicate between xfs_aops.c and xfs_iomap.c.  It's not a very
useful structure - we basically need block offsets above and below
it, but it's in terms of bytes.  Removing it and using the xfs_bmbt_irec
structure instead thus simplifies the code and reduces the stack footprint
of the writeback code.
