[PATCH 0/3] improve error handling for module load

[Claudio Fontana <cfontana@suse.de>]

while investigating a permission issue in accel, where accel-tcg-x86_64.so
was not accessible, I noticed that no errors were produced regarding the
module load failure.

This series attempts to improve module_load_one and module_load_qom_one
to handle the error cases better and produce some errors.

Patch 1 is already reviewed and is about removing an unused existing
argument "mayfail" from the call stack.

Patch 2 is the real meat, and that one I would say is RFC.
Will follow up with comments on the specific questions I have.

Patch 3 finally adds a simple check in accel/, aborting if a module
is not found, but relying on the existing error report from
module_load_qom_one.

Claudio Fontana (3):
  module: removed unused function argument "mayfail"
  module: add Error arguments to module_load_one and module_load_qom_one
  accel: abort if we fail to load the accelerator plugin
