xfs: move more buffer helpers into xfs_buf.c
Move xfsbdstrat and xfs_bdstrat_cb from xfs_lrw.c and xfs_bioerror and xfs_bioerror_relse from xfs_rw.c into xfs_buf.c. This also means xfs_bioerror and xfs_bioerror_relse can be marked static now. Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Alex Elder <aelder@sgi.com>
