[RFC][PATCH 0/3] xip: no struct pages -- summary This short series extendeds one of Nick Piggins patches for the XIP overhaul that we've been kicking around. I'm just hoping to get the API changes reviewed now. I haven't tested this, just compiled what I can. So what I'm doing here is swapping out get_xip_page() for get_xip_mem(). The get_xip_mem() API gives us a kaddr and a pfn. I thought it worked best to force this kaddr and pfn down through the block dev's direct_access() API. I'm really unsure if I understand whether I got the device specific implementations of the new direct_access() right. For those interested I'll be updating my git tree at git.infradead.org/users/jehulber/axfs.git with an updated patch set Monday.
