thanks for comitting this fix so fast.
while running the ltp i stumbled upon another problem, which isn't causing a
panic however. the "testcases/kernel/ipc/ipc_stress/message_queue_test_02_rcv"
test seems to stall at sone point and needs to be killed. the test doesn't get
past this line (message_queue_test_02_rcv.c/line 131):
if (msgrcv (msqid, message, BUF_SIZE, 0, 0) < 0)
sys_error ("msgrcv failed", __LINE__);
i attached a linux_kdump.
cheers.
