[PULL 24/25] vmdk: make vmdk_is_cid_valid a coroutine_fn
Posted by Kevin Wolf 1 year, 11 months ago
From: Paolo Bonzini <pbonzini@redhat.com>

Functions that can do I/O are prime candidates for being coroutine_fns.  Make the
change for the one that is itself called only from coroutine_fns.  Unfortunately
vmdk does not use a coroutine_fn for the bulk of the open (like qcow2 does) so
vmdk_read_cid cannot have the same treatment.
