[PATCH v2 0/3] vhost: cross-endian code cleanup
This series is a new tentative to have cleaner cross-endian code.
Patches 1/3 is new: it fixes a side-effect in case vhost_init_used() fails.
Patch 2/3 comes from v1: it renames cross-endian helpers
Patch 3/3 is new: it simply renames vhost_init_used() as suggested by Michael.
