A customer reported a problem: If a process is using mmap to write to a file on an ext4 filesystem while another process is using direct I/O to write to the same file the first thread may receive a SIGBUS during a page fault. A SIGBUS occurs if the page fault tries to access a page that is entirely beyond the end of the file but in this test case that should not be happening.
