Subject: revert: loop: queue_lock NULL pointer derefence in blk_throtl_exit V1
Date: Fri, 11 Feb 2011 14:59:41 +0200	[thread overview]
Message-ID: <20110211125941.GA4271@swordfish.minsk.epam.com> (raw)

Hello Jens, Andrew

We have accidentally commit "loop: queue_lock NULL pointer 
derefence in blk_throtl_exit V1" applied: ee71a968672a9951aee6014c55511007596425bc

It's not a huge problem, but I think, it's better to have V3 applied 
https://lkml.org/lkml/2011/1/21/158

since V3 targets all the throttle users, not only loop (by moving 
`fall-back' from loop_free to blk_release_queue).

V3 is in Andrew's mmotm as for now 
loop-queue_lock-null-pointer-derefence-in-blk_throtl_exit-v3.patch

Could we please revert ee71a968672a9951aee6014c55511007596425bc when 
loop-queue_lock-null-pointer-derefence-in-blk_throtl_exit-v3 will land 
in the kernel?

Sorry.

Thanks in advance,

        Sergey
