SELinux only grabs a references to dentries during its call to fs_ops->getxattr, which can't last a meaningful length of time (unless the filesystem is busted). It only grabs references to inodes during system initialization, when you couldn't have many in core. Audit, likewise, only grabs a reference to a dentry during execve() and only long enough to run getxattr and does not grab any reference directly to an inode at all. > or whether your backup program (or some other > program running on your system) is keeping lots of directories or > inodes open for some reason.
