Prev: [PATCH] ksz884x: fix return value of netdev_set_eeprom
Next: [PATCH -mm 0/2] misc: don't use sig->count
From: Oleg Nesterov on 23 Mar 2010 11:00
Trivial, use get_nr_threads() helper to read signal->count which
we are going to change.

Like other callers, proc_sched_show_task() doesn't need the exactly
precise nr_threads.
