Subject: NFSv4: Don't call update_changeattr() unless the unlink is successful
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=c40d52fe1c2ba25dcb8cd207c8d26ef5f57f0476;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

NFSv4: Don't call update_changeattr() unless the unlink is successful

If the unlink wasn't successful, then the directory has presumably not
changed.
