[libvirt] [PATCH v2 0/5] Add read error ignore to storage backend vol info APIs

[John Ferlan]

v1 took a simplistic approach:

http://www.redhat.com/archives/libvir-list/2015-October/msg00919.html

but not specific enough according to the review. So adding some extra
complexity of checking for specific errors and flag bits to "ignore" the
error similar to the catch-all openflags VIR_STORAGE_VOL_OPEN_NOERROR for
all the virStorageBackendUpdateVol{Info|TargetInfo|TargetInfoFD} API's
which are used to get the volume capacity, allocation, etc. data.

Along the way an inavertent bug was found and fixed in patch 3 in
virStorageBackendUpdateVolTargetInfo where an error could have been
reported, but not propagated back to the user since 'ret' would have
been 0 after the virStorageBackendUpdateVolTargetInfoFD call.


John Ferlan (5):
  storage: Add readflags for backend error processing
  storage: Add comments for backend APIs
  storage: Handle readflags errors
  storage: Add debug message
  storage: Ignore block devices that fail format detection
