Miklos, Found one memory leak that needs a fix for stable and two missing freeze protections in stacked f_ops. Last patch is not a bugfix, but it fixes a trap that we set for developers back in v4.10 - and you happened to step into. The series passed xfstests -g quick with overlayfs over xfs and ext4 and the usual unionmount testsuite torture. The memory leak was detected with tests overlay/051,053 after I enabled kmemleak on my test setup. Thanks, Amir.
