[libvirt] [PATCH v2 0/6] storage: handle scsi/iscsi error paths better

v1 here: http://www.redhat.com/archives/libvir-list/2015-March/msg01562.html changes: 1/6: Removed the virGetLastError() == NULL check 2/6: New - reading more closely showed an error path without a goto 3/6: New - Adjust return for virStorageBackendSCSINewLun to be able to differentiate real error vs. deciding to return because a stable path could not be determined 4/6: New - Found an unused variable in processLU 5/6: Adjust the logic to return -1 for "real" errors and -2 for errors that are "recoverable". Removed the need for goto cleanup. 6/6: Add check for non-existent stable path at startup (and fail). Add check during refresh for a found non standard stable path that returns no volumes in the pool John Ferlan (6): iscsi: Use error message from virStorageBackendSCSIFindLUs iscsi: Fix exit path for virStorageBackendISCSIFindLUs failure scsi: Adjust return value for virStorageBackendSCSINewLun scsi: Remove unused 'type_path' in processLU scsi: Adjust return values from processLU iscsi: Add checks for non standard stable target.path src/storage/storage_backend_iscsi.c | 33 ++++++++++++++++----- src/storage/storage_backend_scsi.c | 59 ++++++++++++++++++++++++------------- 2 files changed, 64 insertions(+), 28 deletions(-) -- 2.1.0
