Subject: NFS41/flexfiles: update inode after write finishes
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=69f230d907e8c1ca3f9bd528993eeb98f712b0dd;p=deliverable%2Flinux.git

NFS41/flexfiles: update inode after write finishes

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

Does files layout need the same fix as well?
