Subject: bounce limit in mmc?
Date: Mon, 28 Aug 2017 10:48:08 -0700 [thread overview]
Message-ID: <20170828174808.GA8384@infradead.org> (raw)
Hi all, any idea why the mmc driver defaults to bouncing highmem
pages if the device doesn't have a DMA mask? highmem is defined
different on different architectures or even based on config options,
so it seems like a very odd choice.
