nfs_pageio_cond_complete - Conditional I/O completion : pointer to io descriptor : page index

It is important to ensure that processes don't try to take locks on non-contiguous ranges of pages as that might deadlock. This function should be called before attempting to wait on a locked nfs_page. It will complete the I/O if the page index 'index' is not contiguous with the existing list of pages in 'desc'.
