A lot of memory can be consumed by the events generated for the huge or
unlimited queues if there is either no or slow listener. This can cause
system level memory pressure or OOMs. So, it's better to account the
fsnotify kmem caches to the memcg of the listener.
There are seven fsnotify kmem ca
This patchset introduces memcg variant memory allocation functions. The
caller can explicitly pass the memcg to charge for kmem allocations.
Currently the kernel, for __GFP_ACCOUNT memory allocation requests,
extract the memcg of the current task to charge for the kmem allocation.

Fix build errors when INFINIBAND_USER_ACCESS=m and MLX5_INFINIBAND=y.
The build error occurs when the mlx5 driver code attempts to use
USER_ACCESS interfaces, which are built as a loadable module.
Fixes these build errors:
