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.
