Subject: [PATCH] add support for fsck.f2fs
The Nexus 9 uses f2fs for /data. Make sure to properly label
/system/bin/fsck.f2fs so that the appropriate domain transition occurs.
Add support for getattr on devpts, required for fsck.f2fs.
Addresses the following denials:
avc: denied { execute_no_trans } for pid=172 comm="init" path="/system/bin/fsck.f2fs" dev="dm-0" ino=272 scontext=u:r:init:s0 tcontext=u:object_r:system_file:s0 tclass=file permissive=0
avc: denied { getattr } for pid=170 comm="fsck.f2fs" path="/dev/pts/0" dev="devpts" ino=3 scontext=u:r:fsck:s0 tcontext=u:object_r:devpts:s0 tclass=chr_file permissive=1
