IIRC, the original deadlock call chain was when SELinux tried to set the security attribute on a newly created file from the post_create hooks. Looked something like (SELinux) post_create -> reiser_setxattr -> ... -> open_xa_dir -> reiserfs_mkdir -> d_instantiate -> selinux_d_instantiate() -> inode_doinit_with_dentry() -> reiser_getxattr. First reported in http://marc.theaimsgroup.com/?l=linux-kernel&m=108625196416654&w=2, but that only addressed the deadlock issue, not the permission checking problem.
