Oleg Nesterov	8804023061	[PATCH] fix Documentation/accounting/getdelays.c buf size ... getdelays reports a "fatal reply error, errno 258". We don't have enough room for multi-threaded exit (PID + TGID).

Balbir Singh	7d1bdca9b0	[PATCH] Fix getdelays.c - cpumask length and error reporting ... Fix the length passed while (un)registering cpumask. We were passing sizeof the array, make it strlen(). Error value printed in fatal errors should be derived from the message. The message contains an nlmsgerr embedded with an error value. We must report that value to the user.
