2010-11-04block: Allow bdrv_flush to return errorsKevin Wolf1-2/+2
This changes bdrv_flush to return 0 on success and -errno in case of failure. It's a requirement for implementing proper error handle in users of bdrv_flush. Signed-off-by: Kevin Wolf <kwolf@redhat.com> Reviewed-by: Stefan Hajnoczi <stefanha@linux.vnet.ibm.com>
2010-10-22block: Use GCC_FMT_ATTR and fix a format errorStefan Weil1-2/+3
Adding the gcc format attribute detects a format bug which is fixed here. v2: Don't use type cast. BDRV_SECTOR_SIZE is unsigned long long, so %lld should be the correct format specifier.

2010-09-21blkverify: Add block driver for verifying I/OStefan Hajnoczi1-0/+382
The blkverify block driver makes investigating image format data corruption much easier. A raw image initialized with the same contents as the test image (e.g. qcow2 file) must be provided. The raw image mirrors read/write operations and is used to verify that data read from the test image is correct. See docs/blkverify.txt for more information.
