Hi all, I have a bug with OCFS through configfs : to illustrate this, try : while true ; do ls -l /sys/kernel/config/cluster/ocfs2/heartbeat ; done& while true ; do echo 31> /sys/kernel/config/cluster/ocfs2/heartbeat/dead_threshold ; done& So, I have a kernel crash : BUG: unable to handle kernel NULL pointer dereference at 0000000000000040 IP: [<ffffffffa01fd214>]

The only non-fix here is Joel's new configfs convenience macros, but nobody is using them yet, so I think the patch is safe. By the way, these patches (as usual) are all rebased on top of your latest tree. I think that since the vast majority of ocfs2 and configfs patches are self-contained and within a small area of the kernel that this should probably be fine. If you feel otherwise however,

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
