From 5c60e89e71f864033a268ed66933dad0d92f1550 Mon Sep 17 00:00:00 2001 From: Trond Myklebust Date: Sat, 29 Jan 2022 14:03:06 -0500 Subject: [PATCH] NFSv4.2: Fix up an invalid combination of memory allocation flags We should use either GFP_KERNEL or GFP_NOFS, but not both. Also strip GFP_KERNEL_ACCOUNT down to GFP_KERNEL. This memory is shrinkable, so does not need to be limited by kmemcg.
