From cb8285b89f2cf1db866f5c5aae5ce8db7aef41dd Mon Sep 17 00:00:00 2001 From: Yishai Hadas Date: Sun, 8 Jan 2023 17:44:25 +0200 Subject: [PATCH] vfio/hisi: Use GFP_KERNEL_ACCOUNT for userspace persistent allocations Use GFP_KERNEL_ACCOUNT for userspace persistent allocations. The GFP_KERNEL_ACCOUNT option lets the memory allocator know that this is untrusted allocation triggered from userspace and should be a subject of kmem accounting, and as such it is controlled by the cgroup mechanism.
