tcontext=u:object_r:libart_file:s0 tclass=file
avc: granted { read open } for comm="debuggerd64"
path="/system/lib64/libart.so" dev="dm-0" ino=1897

avc: granted { getattr } for comm="debuggerd64"
path="/system/lib64/libart.so" dev="dm-0" ino=1837
scontext=u:r:debuggerd:s0 tcontext=u:object_r:libart_file:s0 tclass=file
Test: Policy compiles. Not a tightening of rules.
