Hello.
I found that accessing namespace_sem from security_inode_create()
causes lockdep warning when compiled with CONFIG_PROVE_LOCKING=y .
sounds like you have an AB-BA deadlock...
sed /you/AppArmor shipped with OpenSuSE 10.1 and 10.2/ :)
Though I don't think this deadlock should occur quite often,
it occurs when it occurs. Care should be taken promptly.
There should be no way around for this problem as its nature.
Passing vfsmount parameter to VFS helper functions and
LSM hooks seems to be a good choice to me.
