From 89c2be8a951654758dffeaaa6272328d9c8f29be Mon Sep 17 00:00:00 2001 From: NeilBrown Date: Mon, 7 Mar 2022 10:41:44 +1100 Subject: NFS: discard NFS_RPC_SWAPFLAGS and RPC_TASK_ROOTCREDS NFS_RPC_SWAPFLAGS is only used for READ requests. It sets RPC_TASK_SWAPPER which gives some memory-allocation priority to requests. This is not needed for swap READ - though it is for writes where it is set via a different mechanism. RPC_TASK_ROOTCREDS causes the 'machine' credential to be used. This is not needed as the root credential is saved when the swap file is opened, and this is used for all IO. So NFS_RPC_SWAPFLAGS isn't needed, and as it is the only user of RPC_TASK_ROOTCREDS, that isn't needed either. Remove both.
