Name:compat_get_user_cpu_mask
Proto:static int compat_get_user_cpu_mask(compat_ulong_t __user *user_mask_ptr, unsigned len, struct cpumask *new_mask)
Type:int
Parameter:
Type | Parameter | Name |
---|---|---|
compat_ulong_t __user * | user_mask_ptr | |
unsigned | len | |
struct cpumask * | new_mask |
179 | If len < pumask_size - size to allocate for a 'struct cpumask' in bytes Then memset(new_mask, 0, pumask_size - size to allocate for a 'struct cpumask' in bytes) |
181 | Else if len > pumask_size - size to allocate for a 'struct cpumask' in bytes Then len = pumask_size - size to allocate for a 'struct cpumask' in bytes |
184 | k = cpumask_bits - get the bits in a cpumask*@maskp: the struct cpumask ** You should only assume nr_cpu_ids bits of this mask are valid. This is* a macro so it's const-correct.(new_mask) |
185 | Return compat_get_bitmap(k, user_mask_ptr, len * 8) |
