[PATCH 4.2 083/134] NFS41/flexfiles: update inode after write finishes

[Greg Kroah-Hartman]

4.2-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Peng Tao <tao.peng@xxxxxxxxxxxxxxx>

commit 69f230d907e8c1ca3f9bd528993eeb98f712b0dd upstream.

Otherwise we break fstest case tests/read_write/mctime.t

Does files layout need the same fix as well?
