This series addresses error handling issues in virtio-gpu and improves
code consistency across the virtio-gpu subsystem.
The first patch fixes a critical bug in virgl_cmd_resource_create_blob()
where an inverted error check causes the function to fail when it should
succeed. This is a standalone bug fix that should be backported.
The second patch improves code consistency by unifying the error checking
style for virtio_gpu_create_mapping_iov() in if-statement contexts across
virtio-gpu files, following the preferred QEMU coding convention.
Changes since v5:
- Reverted changes to virtio-gpu-rutabaga.c to keep CHECK macro usage
consistent with other error checks in the same file
- Updated patch 2 commit message to clarify that CHECK macro patterns
in rutabaga.c are intentionally left unchanged
Changes since v4:
- Split the single patch into two separate patches for better clarity
- Separated the critical bug fix from the style consistency improvements
- The bug fix (patch 1) can now be easily identified and backported
- The consistency improvements (patch 2) are clearly marked as cleanup
Changes since v3:
- Extended consistency improvements to virtio-gpu-rutabaga.c
- Changed CHECK(!ret) to CHECK(ret >= 0) and CHECK(!result) to
CHECK(result >= 0) in rutabaga functions for consistency
- Now covers all virtio-gpu files that use virtio_gpu_create_mapping_iov()
Changes since v2:
- Use 'if (ret < 0)' instead of 'if (ret != 0)' following maintainer's
feedback on preferred QEMU coding style for error checking functions
that return 0 on success and negative on error
- Updated all similar usages across virtio-gpu files for consistency
- Expanded scope from single function fix to codebase-wide style consistency
