Pull ksys_mount() and ksys_dup() removal from Dominik Brodowski: "This small series replaces all in-kernel calls to the userspace-focused ksys_mount() and ksys_dup() with calls to kernel-centric functions: For each replacement of ksys_mount() with do_mount(), one needs to verify that the first and third parameter (char *dev_name, char *type) are strings allocated in kernelspace and that the fifth parameter (void *data) is either NULL or refers to a full page (only occurence in init/do_mounts.c::do_mount_root()). The second and fourth parameters (char *dir_name, unsigned long flags) are passed by ksys_mount() to do_mount() unchanged, and therefore do not require particular care. Moreover, instead of pretending to be userspace, the opening of /dev/console as stdin/stdout/stderr can be implemented using in-kernel functions as well. Thereby, ksys_dup() can be removed for good" [ This doesn't get rid of the special "kernel init runs with KERNEL_DS" case, but it at least removes _some_ of the users of "treat kernel pointers as user pointers for our magical init sequence". One day we'll hopefully be rid of it all, and can initialize our init_thread addr_limit to USER_DS. - Linus ] * 'remove-ksys-mount-dup' of git://git.kernel.org/pub/scm/linux/kernel/git/brodo/linux: fs: remove ksys_dup() init: unify opening /dev/console as stdin/stdout/stderr init: use do_mount() instead of ksys_mount() initrd: use do_mount() instead of ksys_mount() devtmpfs: use do_mount() instead of ksys_mount() |
