[PATCH v2 1/8] iscsi_direct: Make virStorageBackendISCSIDirectGetLun report error properly

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



This function reports error for one of the two error paths. This
is unfortunate as a caller see this function failing but doesn't
know right away if an error was reported.
