This should fix the assert seen from debug kernels, and the NFS oops
reported by Matteo Centonza. Assorted other I/O path problems from the
last couple of days should probably settle down as well.

Modid:  2.4.x-xfs:slinx:91786a
linux/fs/xfs/linux/xfs_lrw.c - 1.88
        - cleanup the eof hole zeroing code to be more straightforward

linux/include/linux/page_buf.h - 1.85
        - changed proto for pagebuf_iozero

linux/fs/pagebuf/page_buf_io.c - 1.75
        - Fix pagebuf_iozero to call the higher level commit_write function and
          bump the inode size as required. Remove the cases were prepare_write 
was
          not being called - as this was broken (assert trip and sometimes 
panic).
