Wysocki" , linux-kernel@vger.kernel.org, linux-raid@vger.kernel.org, linux-fsdevel@vger.kernel.org, linux-api@vger.kernel.org List-Id: linux-raid.ids Hi Al and Linus, currently a lot of the file system calls in the early in code (and the devtmpfs kthread) rely on the implicit set_fs(KERNEL_DS) during boot. This is one of the few last remaining places we need to deal with to kill off set_fs entirely, so this series adds new helpers that take kernel pointers. These helpers are in init/ and marked __init and thus will be discarded after bootup. A few also need to be duplicated in devtmpfs, though unfortunately. The series sits on top of my previous "decruft the early init / initrd / initramfs code v2" series. Git tree: git://git.infradead.org/users/hch/misc.git init_path Gitweb: http://git.infradead.org/users/hch/misc.git/shortlog/refs/heads/init_path Changes since v1: - avoid most core VFS changes - renamed the functions and move them to init/ and devtmpfs - drop a bunch of cleanups that can be submitted independently now Diffstat:
