Actually ocfs2_sysfile_cluster_lock_key is only used if we enable CONFIG_DEBUG_LOCK_ALLOC.

Hi, here comes the next version of OCFS2 lockdep support. I've dropped patches with fixes from the series since they were already merged. As Joel suggested, I've simplified the main patch a bit so that we don't have ifdefs around lock declarations and there are also a few other minor improvements. Honza

Hi, the first four patches in this series fix locking problems in OCFS2 quota code (three of them can lead to potential deadlocks). The fifth patch reorders ip_alloc_sem for directories to be acquired before localalloc locks. Mark would you please merge these? The last two patches implement lockdep annotations for OCFS2 cluster locks. We annotate all the cluster locks except for special ones

The following is a patch I've been working on to support a "ChrootUser" option in the sshd_config file. I was looking for a way to offer sftp access and at the same time restict interactive shell access. This patch is a necessary first step (IMO). It applies clean with 'patch -l'. Also attached is a shell script that helps to build a chrooted home dir on a RedHat 7.2

Hi, I'm resending this patch series. It's rediffed against linux-next branch of Joel's git tree. The first four patches are obvious fixes of deadlocks in quota code and should go in as soon as possible. The other three patches implement lockdep support for OCFS2 cluster locks. So you can have a look whether the code make sence to you and possibly merge them. They should be NOP when

OpenSSH 3.0 has just been released. It will be available from the mirrors listed at http://www.openssh.com/ shortly. OpenSSH is a 100% complete SSH protocol version 1.3, 1.5 and 2.0 implementation and includes sftp client and server support. This release contains many portability bug-fixes (listed in the ChangeLog) as well as several new features (listed below). We would like to thank the

Hi, here is the second version of OCFS2 quota fixes with Joel's comments fixed. Also I've added a patch defining counts of credits for quota operations as Joel asked. Honza

Hi, I did some more in-depth testing of OCFS2 quota code, especially with ECC feature enabled and spotted some problems. First four patches fix them. I need the fifth patch to be able to mount OCFS2 filesystem with 2.6.31-rc3. The sixth patch fixes a potential problem when quota syncing interval is updated while the cluster is running (which is not possible currently). Joel, could you please
