Hi, The following patches fix few bugs/APIs in configfs. The third one depends on the patch introducing configfs_dirent_lock previously submitted in http://lkml.org/lkml/2008/6/12/232 Louis -- Dr Louis Rilling Kerlabs Skype: louis.rilling Batiment Germanium Phone: (+33|0) 6 80 89 08 23 80 avenue des Buttes de Coesmes http://www.kerlabs.com/ 35700 Rennes

The following patches were made over Linus tree and also apply over mst tree's vhost branch. The patches fix an issue where management operations like LUN mapping/unmapping and device addition hang for 30 seconds or up to N minutes depending on the device. The problem is that we use a global mutex to protect the list of tpgs but we hold that mutex during those management operations. So if you

The following patches were made over Linus tree. The patches fix 3 issues: 1. If a user performs LIO LUN unmapping before the endpoint has been cleared then we can end up trying to free a bogus tmf struct if the TMF is still exucuting when we do the unmap. 2. If vhost_scsi_setup_vq_cmds fails we can leave the tpg->vhost_scsi pointer set and we can end up trying to access a freed struct. 3.

I'm running a bit late with the e-mail this time around, but I think that's ok since there really isn't any major new features here - the bulk of the Ocfs2 update is bug fixes, or cleanups. The same goes for configfs. The only two things that could be described as features would be: - Sunil has updated Ocfs2 to provide even more live cluster locking information via debugfs. - Joel
