Subject: NFSv4: Return any delegations before sillyrenaming the file
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=34ea818846e6cccdd6e05354ab8c8a6d7e34657a;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

NFSv4: Return any delegations before sillyrenaming the file

 I missed this one... Any form of rename will result in a delegation
 recall, so it is more efficient to return the one we hold before
 trying the rename.
