| H A D | container.c | 0886196c Sun Jan 08 09:44:24 CST 2023 Jason Gunthorpe <jgg@nvidia.com> vfio: 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.
The way to find the relevant allocations was for example to look at the
close_device function and trace back all the kfrees to their
allocations.
