Now we have memory space available to a kunit test case log exposed via debugfs limited to 2048 bytes, while some parametrized test cases, e.g., drm_framebuffer.drm_test_framebuffer_create, need more. For this reason, debugfs results from affected test cases get truncated silently, and external tools that rely on parsing of debugfs results can fail.
Increase kunit test case log size limit to 4096 bytes.

There's a patch series we're hoping to take for 6.7 which allows the log to grow to fit whatever's written into it, which should make this patch obsolete: https://lore.kernel.org/linux-kselftest/20230828104111.2394344-1-rf@opensour...
Would that work for you?
Yeah, that's going to work perfectly for us, thank you.
