15 * A struct pid is the kernel's internal notion of a process identifier.
17 * there are processes attached to it the struct pid lives in a hash
19 * quickly from the numeric pid value. The attached processes may be
20 * quickly accessed by following pointers from struct pid.
23 * problem. The process originally with that pid may have exited and the
24 * pid allocator wrapped, and another process could have come along
25 * and been assigned that pid.
32 * a struct pid is about 64 bytes.
34 * Holding a reference to struct pid solves both of these problems.
