My test case isn't running well on net-next. Seems most
of the file-io processes are hung trying to open a file:
[root@lf1011-12060006 lanforge]# cat /proc/10612/stack
[<ffffffff8115fadb>] do_last+0x1db/0xa4e
[<ffffffff8116090b>] path_openat+0xcb/0x363
[<ffffffff81160ca8>] do_filp_open+0x38/0x84
[<ffffffff81153bfc>] do_sys_open+0x6d/0xff
[<ffffffff81153cbb>] sys_open+0x1c/0x1e
[<ffffffff8154f629>] system_call_fastpath+0x16/0x1b
[<ffffffffffffffff>] 0xffffffffffffffff
I'm going back to 3.7.3 and will try to learn some more
about what it's doing there.
Thanks,
Ben
