Re: [PATCH v6 3/8] dma: swiotlb: Track whether the pool size was explicitly set

[sashiko-bot@kernel.org]

> swiotlb_adjust_size() must not override a pool size supplied through the
> swiotlb= command-line parameter.
> 
> Currently, it determines whether a size was supplied by comparing
> default_nslabs with IO_TLB_DEFAULT_SIZE. This fails when the user
> explicitly requests the compiled-in default size, allowing the request
> to be overwritten by automatic pool sizing.
> 
> Record whether swiotlb= supplied a numeric size in swiotlb_cmdline_size_set
> and check that flag directly before adjusting the pool size.
