πŸŽ€ NAME πŸŽ€

okay bestie, we're flipping through the Kernel API Manual, section 9, and this little page is dm_test_col...x_bad_length(9) β€” yes that's the truncated header, she's shy, the real name is right below πŸ‘‡

dm_test_colorop_3x4_matrix_bad_length β€” wrong blob length: must return -EINVAL πŸ’…

bestie heads-up: this tester's whole personality is that bad-length blob situation. Give it a wrong-length blob, expect -EINVAL back. That's the assignment πŸ’€βœ¨

and that's the page 🫢 sourced from ./drivers/gpu/drm/amd/display/..., dated October 2026, signed off under the Kernel API Manual umbrella as dm_test_col...x_bad_length(9) β€” iconic, no notes, periodt πŸ’–πŸ‘‘
