Subject: [PATCH 5.17 607/772] NFS: Convert GFP_NOFS to GFP_KERNEL
From: Trond Myklebust <trond.myklebust@...merspace.com>
[ Upstream commit da48f267f90d9dc9f930fd9a67753643657b404f ]
Assume that sections that should not re-enter the filesystem are already
protected with memalloc_nofs_save/restore call, so relax those GFP_NOFS
instances which might be used by other contexts.
