[PATCH v2 00/20] VFIO: misc cleanups part2
Posted by Zhenzhong Duan 6 months, 1 week ago
Hi

This is the last round of cleanup series to change functions in hw/vfio/
to return bool when the error is passed through errp parameter.

The first round is at 
https://lists.gnu.org/archive/html/qemu-devel/2024-05/msg01147.html

I see Cédric is also working on some migration stuff cleanup,
so didn't touch migration.c, but all other files in hw/vfio/ are cleanup now.

Patch1 and patch20 are fix patch, all others are cleanup patches.

Test done on x86 platform:
vfio device hotplug/unplug with different backend
reboot

This series is rebased to https://github.com/legoater/qemu/tree/vfio-next

Thanks
Zhenzhong

Changelog:
v2:
- add patch17 to use g_autofree in all callsite of vfio_get_region_info() (Cédric)
- add patch18 to use g_autofree in vfio_probe_igd_bar4_quirk()
- add patch19 to drop local err in vfio_ccw_realize() (Cédric)
- add patch20 to fix a bug I just found
- add R-B
