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

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).

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)

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
