From e713d0dab21a68500720e222fa02567fc7dfb14b Mon Sep 17 00:00:00 2001 From: Sukadev Bhattiprolu Date: Thu, 10 May 2007 22:22:58 -0700 Subject: attach_pid() with struct pid parameter attach_pid() currently takes a pid_t and then uses find_pid() to find the corresponding struct pid. Sometimes we already have the struct pid. We can then skip find_pid() if attach_pid() were to take a struct pid parameter.
