Subject: [PATCH] Fix building with Linux kernel 2.6.32 and later.
With commit 18f2ee705d98034b0f229a3202d827468d4bffd9 of the Linux kernel,
the sync_page_range() function has been removed.
This patch changes it to filemap_write_and_wait_range() as done for the XFS
driver in the kernel (commit af0f4414f343429971d33b0dd8dccc85c1f3dcd2).
