Re: [libvirt] [PATCHv2 2/4] Make virStorageBackendCopyToFD return -errno.

Previously virStorageBackendCopyToFD would simply return -1 on error. This made the error return from one of its callers inconsistent (createRawFileOpHook is supposed to return -errno, but if virStorageBackendCopyToFD failed, createRawFileOpHook would just return -1). Since there is a useful errno in every case of error return from virStorageBackendCopyToFD, and since the other uses of that function ignore the return code (beyond simply checking to see if it is < 0), this is a safe change. --- src/storage/storage_backend.c | 9 +++++++-- 1 files changed, 7 insertions(+), 2 deletions(-)
