Miklos,

This series fixes a v4.19 regression.

It also provides correct semantics w.r.t RDONLY open counter
that Bruce also needed for nfsd.

I marked both patches for stable v4.19.

I verified the changes using modified LTP fcntl tests [1],
which I ran over xfs and overlayfs.

Thanks,
Amir.

  vfs: replace i_readcount with a biased i_count
  locks: eliminate false positive conflicts for write lease
