Subject: NFSv4.1/pnfs: Ensure we send layoutcommit before return-on-close
X-Git-Tag: v4.1-rc1~6^2~19
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=7140171ea9be4143736c35acf6f31b6feb195ca0;p=platform%2Fkernel%2Flinux-exynos.git

NFSv4.1/pnfs: Ensure we send layoutcommit before return-on-close

We must not send a close or delegreturn that would result in a
return-on-close of the layout without ensuring that we've also
sent the necessary layoutcommit.
