Hi all,
during booting 3.8.0 I hit this:
BUG: sleeping function called from invalid context at
kernel/rcutree.c:2208
in_atomic(): 1, irqs_disabled(): 0, pid: 1976, name: multipath
Pid: 1976, comm: multipath Not tainted 3.8.0-default+ #18

and several others of that ilk.
System itself doesn't seem to be affected, but we might want to look
into it.

It seems the same issue with this:
[PATCH repost] blkcg: fix "scheduling while atomic" in blk_queue_bypass_start
https://patchwork.kernel.org/patch/2183891/
I've been waiting for Jens to pick it up.

I just offloaded the bigger chunk for 3.9, there will be a 2nd round
after -rc1 where this is going to be included (amongst other things).

Hi,
my RHEL 5.9 host system has several SCSI LUNs attached. For some reason
the /dev/disk/by-path directory is missing...Does anybody has an idea what
went wrong
or how to debug. Other RHEL 5.9 system are fine.
Regards,
Christian May

It seems the above patch hasn't yet included in 3.9-rc6.
Could you take it?
(Maybe for 3.10, if it's too late for 3.9)
