From: Zhao Liu <zhao1....@intel.com> Hi list,
This series is the second part to add missing ERRP_GUARD() for error_prepend(), which is based on my first part: <20240228163723.1775791-1-zhao1....@linux.intel.com> [1] 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 and the part 1 [1], all error_prepend() will follow the above usage rules. I think it's particularly noteworthy that two cases of error_prepend() with &error_fatal are recognized in this series (patch 14 & patch 15). In fact, error_append_hint() also need ERRP_GUARD(), but very unfortunately, I realized that in most usage scenarios in QEMU, it doesn't work with ERRP_GUARD() ;-( ... Maybe need to clean it up in the future and add ERRP_GUARD() to error_append_hint() as well. The cleanup looks very trivial and welcome your feedback!
