From 1142362ff606ab7a1262d7d6f1f9be2205825065 Mon Sep 17 00:00:00 2001 From: Brian Behlendorf Date: Fri, 31 Mar 2023 09:43:54 -0700 Subject: Use vmem_zalloc to silence allocation warning The kmem allocation in zfs_prune_aliases() will trigger a large allocation warning on systems with 64K pages. Resolve this by switching to vmem_alloc() which internally uses kvmalloc() so the right allocator will be used based on the allocation size.
