Subject: [PATCH 2/5] io_uring/rsrc: free io_rsrc_node using kfree()
Date: Fri, 28 Feb 2025 16:59:11 -0700 [thread overview]
Message-ID: <20250228235916.670437-2-csander@purestorage.com> (raw)
In-Reply-To: <20250228235916.670437-1-csander@purestorage.com>
io_rsrc_node_alloc() calls io_cache_alloc(), which uses kmalloc() to
allocate the node. So it can be freed with kfree() instead of kvfree().
