💅 dm_test_fbc_...o_compressor(9) 💅
okay so welcome to the Kernel API Manual page for dm_test_fbc_...o_compressor(9), bestie. this is a tiny test page with big "specific little guy" energy, and we're gonna read it like a group chat. 💖
✨ NAME ✨
dm_test_fbc_init_no_compressor — the test that checks fbc_init is a no-op when there’s no compressor. that's the whole assignment, and it ate. 💅
🌸 SYNOPSIS 🌸
the signature, untouched and iconic:
void dm_test_fbc_init_no_compressor (struct kunit *test );🎀 ARGUMENTS 🎀
test— the KUnit test context. one arg, serving context realness. 🫶
