pstore file system labeling

pstore(persistent store) have been applied since kernel 3.5
We need to label the pstore-fs in order to use Android with kernel 3.5 or upper version.
My kernel version is 3.10 and I got the below denial log when I ran the "df" command on the adb shell.

type=1400 msg=audit(1388540540.220:18): avc: denied { getattr } for pid=7296 comm="df" name="/" dev="pstore" ino=7703 scontext=u:r:init:s0 tcontext=u:object_r:unlabeled:s0 tclass=filesystem

And the below log is also shown during booting

type=1400 msg=audit(1388539193.750:4): avc: denied { mount } for pid=2844 comm="mount" name="/" dev="pstore" ino=11393 scontext=u:r:init_shell:s0 tcontext=u:object_r:unlabeled:s0 tclass=filesystem
