[Qemu-devel] [PATCH v5 04/11] block: remove 'x' prefix from experimental bitmap APIs

[John Snow <jsnow@redhat.com>]

The 'x' prefix was added because I was uncertain of the direction we'd
take for the libvirt API. With the general approach solidified, I feel
comfortable committing to this API for 4.0.
