CVE-2023-54013: In the Linux kernel, the following vulnerability has been resolved:  interconnect: Fix locking for runpm vs reclaim  For cases where icc_bw_set() can be called in callbaths that could deadlock against shrinker/reclaim, such as runpm resume, we need to decouple the icc locking.  Introduce a new icc_bw_lock for cases where we need to serialize bw aggregation and update to decouple that from paths that require memory allocation such as node/link creation/ destruction.
