I found SELinux didn't support reiserfs yet! So I made a change in Makefile and policy.conf. I attach these files, but I'm not sure this is enough.
Created attachment 86845 [details] reiserfs support for SELinux (/etc/security/selinux/src/policy/Makefile)
Created attachment 86846 [details] reiserfs support for SELinux /etc/security/selinux/src/policy/policy.conf It's too large, so gzipped
Reassigning to maintainer.
Reiserfs kernel support for SELinux is incomplete, so it is unusable.
Do you mean reiserfs support of original SELinux is incomplete? Or Gentoo's SELinux support for reiserfs support is incomplete?
ok, I found a description at http://www.crypt.gen.nz/selinux/faq.html
Upstream kernel support is broken.
