I have the following call tree:

Oct 22 22:35:36 goat kernel:  [<c0106d93>] syscall_call+0x7/0xb

and this is the code:
static int __fscap_lookup(struct vfsmount *mnt, struct nameidata *nd)
{
	static char name[] = ".capabilities";
	nd->mnt = mntget(mnt);
	nd->dentry = dget(mnt->mnt_sb->s_root);
	nd->flags = 0;
	return path_walk(name, nd);
}

What does .text.lock.namei and name.810 mean?
Is there a way to get the line number out of these hex values?

TIA
Regards, Olaf.
