From 0af6e690f0d4e8196f6cfa10bad5c9ffff565d9b Mon Sep 17 00:00:00 2001 From: "J. Bruce Fields" Date: Wed, 21 Feb 2018 15:11:03 -0500 Subject: [PATCH] nfsd: factor out common delegation-destruction code Pull some duplicated code into a common helper. This changes the order in destroy_delegation a little, but it looks to me like that shouldn't matter. Signed-off-by: J.
