Subject: xfs: store xfs_mount in the buftarg instead of in the xfs_buf
X-Git-Tag: v2.6.37-rc1~162^2~24

xfs: store xfs_mount in the buftarg instead of in the xfs_buf

Each buffer contains both a buftarg pointer and a mount pointer. If
we add a mount pointer into the buftarg, we can avoid needing the
b_mount field in every buffer and grab it from the buftarg when
needed instead. This shrinks the xfs_buf by 8 bytes.
