Please submit patches using subject lines reflecting the style for the subsystem, this makes it easier for people to identify relevant patches. Look at what existing commits in the area you're changing are doing and make sure your subject lines visually resemble what they're doing. There's no need to resubmit to fix this alone. > ***NOTE*** > Any confused maintainers may want to read the cover note here for context: > https://lore.kernel.org/all/20241014105514.3206191-1-ryan.roberts@xxxxxxx/ As documented in submitting-patches.rst please send patches to the maintainers for the code you would like to change. The normal kernel workflow is that people apply patches from their inboxes, if they aren't copied they are likely to not see the patch at all and it is much more difficult to apply patches. > -static const struct snd_pcm_hardware dummy_dma_hardware = { > +static DEFINE_GLOBAL_PAGE_SIZE_VAR_CONST(struct snd_pcm_hardware, dummy_dma_hardware, { > /* Random values to keep userspace happy when checking constraints */ > .info = SNDRV_PCM_INFO_INTERLEAVED | > SNDRV_PCM_INFO_BLOCK_TRANSFER, > @@ -107,7 +107,7 @@ static const struct snd_pcm_hardware dummy_dma_hardware = { > .period_bytes_max = PAGE_SIZE*2, > .periods_min = 2, > .periods_max = 128, > -}; > +}); It's probably better to just use PAGE_SIZE_MAX here and avoid the deferred patching, like the comment says we don't particularly care what the value actually is here given that it's a dummy.
