2010-04-02tty: release_one_tty() forgets to put pidsOleg Nesterov1-0/+2
release_one_tty(tty) can be called when tty still has a reference to pgrp/session. In this case we leak the pid.

2010-04-01bonding: fix potential deadlock in bond_uninit()Amerigo Wang1-12/+14
bond_uninit() is invoked with rtnl_lock held, when it does destroy_workqueue() which will potentially flush all works in this workqueue, if we hold rtnl_lock again in the work function, it will deadlock. So move destroy_workqueue() to destructor where rtnl_lock is not held any more, suggested by Eric. Signed-off-by: WANG Cong <amwang@redhat.com> Cc: Jay Vosburgh <fubar@us.ibm.com> Cc: "David S.

This allows arch code could decide the way to reserve the ibft. And we should reserve ibft as early as possible, instead of BOOTMEM stage, in case the table is in RAM range and is not reserved by BIOS (this will often be the case.)

2010-04-01ide: Must hold queue lock when requeueingHerbert Xu1-1/+1

2010-04-01ide: Requeue request after DMA timeoutHerbert Xu2-1/+2
I noticed that my KVM virtual machines were experiencing IDE issues resulting in processes stuck on waiting for buffers to complete. The root cause is of course race conditions in the ancient qemu backend that I'm using. However, the fact that the guest isn't recovering is a bug. I've tracked it down to the change made last year to dequeue requests at the start rather than at the end in the IDE layer. commit 8f6205cd572fece673da0255d74843680f67f879 Author: Tejun Heo <tj@kernel.org> Date: Fri May 8 11:53:59 2009 +0900 ide: dequeue in-flight request The problem is that the function ide_dma_timeout_retry does not requeue the current request, causing one request to be lost for each DMA timeout. This patch fixes this by requeueing the request. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S. Miller <davem@davemloft.net>
