[PATCH v2 00/29] Cleanup up to fix missing ERRP_GUARD() for error_prepend()

[Zhao Liu <zhao1.liu@linux.intel.com>]

From: Zhao Liu <zhao1.liu@intel.com>

Hi,

This series is the v2 to add missing ERRP_GUARD() for error_prepend(),
which collects the previous v1 part 1 [1] and v1 part 2 (and excludes
the 4 patches that have already been merged).

The @errp's second restriction (in qapi/error) said:

* Without ERRP_GUARD(), use of the @errp parameter is restricted:
...
* - It should not be passed to error_prepend() or
*   error_append_hint(), because that doesn't work with &error_fatal.
* ERRP_GUARD() lifts these restrictions.

With this series, all error_prepend() will follow the above usage rules.

In this series, 2 cases of error_prepend() with &error_fatal are
recognized (patch 30 & patch 31).

And there are some remaining TODOs:
* follow-up cleanup for related @err use cases. (Suggested by Thomas)
* continue to cleanup error_append_hint().


The cleanup looks very trivial and thanks for your review!
