From 5bd5f5812bfa753218e02cb773e06ede48055798 Mon Sep 17 00:00:00 2001 From: Akinobu Mita Date: Wed, 9 May 2007 02:34:51 -0700 Subject: [PATCH] sunrpc: fix error path in module_init register_rpc_pipefs() needs to clean up rpc_inode_cache by kmem_cache_destroy() on register_filesystem() failure. init_sunrpc() needs to unregister rpc_pipe_fs by unregister_rpc_pipefs() when rpc_init_mempool() returns error.
