Subject: [PATCH] net/mlx5: convert miss_list allocation to kvmalloc_array()
Date: Mon, 1 Jun 2026 15:37:58 -0400 [thread overview]
Message-ID: <20260601193758.626537-1-william@theesfeld.net> (raw)
dr_icm_buddy_init_ste_cache() allocates the per-buddy miss_list using
the open-coded kvmalloc(n * sizeof(*p), ...) form. The neighbouring
allocations in the same function already use the kvcalloc()/
kvzalloc_objs() forms; switch this last one to kvmalloc_array() for
consistency and for the size_mul overflow check that kvmalloc_array()
performs.
The semantics are unchanged: kvmalloc_array() returns a non-zeroed
buffer, just like the previous kvmalloc() call. Existing callers of
buddy->miss_list initialise each list_head before use.
