Chi Zhiling 03222db82a ocfs2: fix unexpected zeroing of virtual disk
In a guest virtual machine, we found that there is unexpected data zeroing
problem detected occassionly:

XFS (vdb): Mounting V5 Filesystem
XFS (vdb): Ending clean mount
XFS (vdb): Metadata CRC error detected at xfs_refcountbt_read_verify+0x2c/0xf0, xfs_refcountbt block 0x200028
XFS (vdb): Unmount and run xfs_repair
XFS (vdb): First 128 bytes of corrupted metadata buffer:

XFS (vdb): metadata I/O error in "xfs_trans_read_buf_map" at daddr 0x200028 len 8 error 74
XFS (vdb): Error -117 recovering leftover CoW allocations.
XFS (vdb): xfs_do_force_shutdown(0x8) called from line 994 of file fs/xfs/xfs_mount.c.  Return address = 000000003a53523a
XFS (vdb): Corruption of in-memory data detected.  Shutting down filesystem
XFS (vdb): Please umount the filesystem and rectify the problem(s)

It turns out that the root cause is from the physical host machine.  More
specifically, it is caused by the ocfs2.

when the page_size is 64k, the block should advance by 16 each time
instead of 1.  This will lead to a wrong mapping from the page to the
disk, which will zero some adjacent part of the disk.
