qemu-io should behave like a guest, therefore it should use BlockBackend to access the block layer. There are a couple of places where that is infeasible: First, the bdrv_debug_* functions could theoretically be mirrored in the BlockBackend, but since these are functions internal to the block layer, they should not be visible externally (qemu-io as a test tool is exempt from this). Second, bdrv_get_info() and bdrv_get_specific_info() work on a single BDS alone, therefore they should stay BDS-specific. Third, bdrv_is_allocated() mainly works on a single BDS as well. Some data may be passed through from the BDS's file (if sectors which are apparently allocated in the file are not really allocated there but just zero). [Fixed conflicts around block_acct_start() usage from Fam Zheng's "qemu-io: Account IO by aio_read and aio_write" commit. Use BlockBackend and blk_get_stats() instead of BlockDriverState. --Stefan] Signed-off-by: Max Reitz <mreitz@redhat.com> Reviewed-by: Eric Blake <eblake@redhat.com> Message-id: 1423162705-32065-14-git-send-email-mreitz@redhat.com Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com> |
