[libvirt] [PATCH v2 0/4] Fix VolOpen error reporting

In https://bugzilla.redhat.com/show_bug.cgi?id=1080613 , something is causing StorageVolGetXML to fail, but it's not raising any error message. Code inspection found that most users of VolOpen are susceptible to error reporting issues. The first 3 patches are some code reorganization and cleanups that make it easier to identify the VolOpen callers. Patch 4 fixes up the reporting issue. v2: Jan's suggestion to only report an error if caller passed in VOL_OPEN_ERROR Cole Robinson (4): storage: Rename UpdateVolInfoFlags to UpdateVolInfo storage: move block format lookup to shared UpdateVolInfo storage: Rename VolOpenCheckMode to VolOpen storage: Report error from VolOpen if proper flag is passed src/storage/storage_backend.c | 260 ++++++++++++++++++---------------- src/storage/storage_backend.h | 18 +-- src/storage/storage_backend_disk.c | 3 +- src/storage/storage_backend_fs.c | 25 ++-- src/storage/storage_backend_logical.c | 11 +- src/storage/storage_backend_mpath.c | 36 +---- src/storage/storage_backend_scsi.c | 43 +----- 7 files changed, 175 insertions(+), 221 deletions(-) -- 1.8.5.3
