When running test 078 against a 4k logical block sized disk, it fails in xfs_repair. The problem is that xfs_repair is passed the loopback filename instead of the actual loop device. This means that it opens the file O_DIRECT, and tries to do 512 byte aligned I/O to a 4k sector device. The loop device, for better or for worse, will do buffered I/O, and thus does not suffer from the same problem. So, the attached patch sets up the loop device and passes that to xfs_repair. This resolves the issue on my test system. Comments are more than welcome. Signed-off-by: Jeff Moyer <jmoyer@redhat.com> Signed-off-by: Christoph Hellwig <hch@lst.de>
