Date: Mon, 16 Apr 2012 17:33:23 -0700 From: H Hartley Sweeten <hartleys@...ionengravers.com> To: Linux Kernel <linux-kernel@...r.kernel.org> CC: <akpm@...ux-foundation.org> Subject: [RFC PATCH 0/2] init: make sure syscall arguments are marked __user where needed When using syscall routines in the kernel, some of the arguments should be user pointers but are missing the __user markup. This produces a number of sparse warnings of the format: warning: incorrect type in argument 1 (different address spaces) expected char [noderef] <asn:1>*dev_name got char *name Wrap the syscall routines in the private do_mounts.h header so that the appropriate __user markups are added for the init mount code.
