Revision 60e69eed85bb7b5198ef70643b5895c26ad76ef7 authored by Mike Galbraith on 07 April 2014, 08:55:15 UTC, committed by Ingo Molnar on 11 April 2014, 08:39:15 UTC
Sasha reported that lockdep claims that the following commit:
made numa_group.lock interrupt unsafe:
156654f491dd ("sched/numa: Move task_numa_free() to __put_task_struct()")
While I don't see how that could be, given the commit in question moved
task_numa_free() from one irq enabled region to another, the below does
make both gripes and lockups upon gripe with numa=fake=4 go away.
