Subject: can we finally kill off CONFIG_FS_DAX_LIMITED
Date: Fri, 20 Aug 2021 07:43:40 +0200 [thread overview]
Message-ID: <20210820054340.GA28560@lst.de> (raw)
Hi all,
looking at the recent ZONE_DEVICE related changes we still have a
horrible maze of different code paths. I already suggested to
depend on ARCH_HAS_PTE_SPECIAL for ZONE_DEVICE there, which all modern
architectures have anyway. But the other odd special case is
CONFIG_FS_DAX_LIMITED which is just used for the xpram driver. Does
this driver still see use? If so can we make it behave like the
other DAX drivers and require a pgmap? I think the biggest missing
part would be to implement ARCH_HAS_PTE_DEVMAP for s390.
