[libvirt] [PATCH v4 0/4] qemu: Report better error on dump/migrate failure

[Andrea Bolognani]

Changes from [v3]:

* Make sure errors from virFileWrapperFdClose() result in an
  overall failure being bubbled up;
* don't call virReportError() unless the function is going to
  report the failure through its return code as well;
* revert b0c3e931804a more thoroughly.

Changes from [v2]:

* Move error reporting from virFileWrapperFdFree() to
  virFileWrapperFdClose().

Changes from [v1]:

* Use VIR_FREE() followed by VIR_ALLOC_N() instead of manually
  setting the last (and only) byte of the array returned by
  VIR_REALLOC_N() to zero.
