Hi,
I realized that if one of the children returns an error during
co_block_status() then we should not pass the error immediately to the
caller, because that's a situation that Quorum should be able to
handle.
The new version of the patch takes the simpler approach of falling
back to returning BDRV_BLOCK_DATA, as if Quorum did not implement
bdrv_co_block_status(). This will force the caller to try to read the
actual data and the normal Quorum voting and error handling process
will be used.
