[PATCH OLK-5.10] mm: memcontrol: do not miss MEMCG_MAX events for enforced allocations
by Cai Xinchen 13 May '24

From: Roman Gushchin <roman.gushchin(a)linux.dev> mainline inclusion from mainline-v6.0-rc1 commit d6e103a757fa7876e7ded76128d5dffe12402ab9 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I9ORR4 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- Yafang Shao reported an issue related to the accounting of bpf memory: if a bpf map is charged indirectly for memory consumed from an interrupt context and allocations are enforced, MEMCG_MAX events are not raised. It's not/less of an issue in a generic case because consequent allocations from a process context will trigger the direct reclaim and MEMCG_MAX events will be raised. However a bpf map can belong to a dying/abandoned memory cgroup, so there will be no allocations from a process context and no MEMCG_MAX events will be triggered.

As per the comment in device_register(), callers should use put_device() to give up the reference in the error path. So fix this by calling put_device() in the error path so that the name can be freed in kobject_cleanup(). As a result of this, put_device() in the error path of ntb_register_device() is removed and the actual error is returned.
