5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Vasily Averin <vasily.averin@xxxxxxxxx>
[ Upstream commit 42193ffd79bd3acd91bd947e53f3548a3661d0a1 ]
nft_*.c files whose NFT_EXPR_STATEFUL flag is set on need to
use __GFP_ACCOUNT flag for objects that are dynamically
allocated from the packet path.
Such objects are allocated inside nft_expr_ops->init() callbacks
executed in task context while processing netlink messages.
In addition, this patch adds accounting to nft_set_elem_expr_clone()
used for the same purposes.
