dm_test_fill...aspect_ratio(9)
β¨ NAME β¨
okay bestie, welcome to the dm_test_fill...aspect_ratio(9) page from the Kernel API Manual β yes the title is literally abbreviated with three dots, it's giving mysterious, we love that for her π
This function is dm_test_fill_stream_aspect_ratio β the one that tests the aspect ratio mapped from the mode. That's the whole vibe. Short king. π
π SYNOPSIS π
void dm_test_fill_stream_aspect_ratio (struct kunit *test );
no return value, it's a void girlie β she does the work and simply leaves π
(keep that space before the paren and before the closing paren, that's just how she's written, don't come for her)
πΈ ARGUMENTS πΈ
testβ the KUnit test context, aka the little β¨test universeβ¨ this thing runs inside. That's it. That's the whole argument list. One (1) bestie.
