Hi david,
It seems that v8 patch I sent last week is missed and commit in misc-next
tree is also a bit updated from v7, so I resend the fix as a separate patch.
Please fold this patch to current misc-next (head is the commit to be fixed:
"btrfs: Add unprivileged version of ino_lookup ioctl").
Thanks,
Tomohiro Misono
