const unsigned long __user *nmask
unsigned longmaxnode
unsigned intflags
1427  start等于Architectures that support memory tagging (assigning tags to memory regions,* embedding these tags into addresses that point to these memory regions, and* checking that the memory and the pointer tags match on memory accesses)(start)
1428  mode_flags等于mode按位与MPOL_MODE_FLAGS is the union of all possible optional mode flags passed to* either set_mempolicy() or mbind().
1429  mode与等于MPOL_MODE_FLAGS is the union of all possible optional mode flags passed to* either set_mempolicy() or mbind().的反
1430  如果mode大于等于MPOL_MAX则返回:负EINVAL
1432  如果mode_flags按位与Flags for set_mempolicy 且mode_flags按位与MPOL_F_RELATIVE_NODES则返回:负EINVAL
1435  err等于Copy a node mask from user space.
1436  如果err则返回:err
1438  返回:do_mbind(start, len, mode, mode_flags, & nodes, flags)
