From e4eff1a622edd6ab7b73acd5d8763aa2fa3fee49 Mon Sep 17 00:00:00 2001 From: Trond Myklebust Date: Sat, 14 Jul 2007 15:39:58 -0400 Subject: SUNRPC: Clean up the sillyrename code Fix a couple of bugs: - Don't rely on the parent dentry still being valid when the call completes. Fixes a race with shrink_dcache_for_umount_subtree() - Don't remove the file if the filehandle has been labelled as stale. Fix a couple of inefficiencies - Remove the global list of sillyrenamed files. Instead we can cache the sillyrename information in the dentry->d_fsdata - Move common code from unlink_setup/unlink_done into fs/nfs/unlink.c Signed-off-by: Trond Myklebust --- fs/nfs/nfs3proc.c | 38 +++++++++----------------------------- 1 file changed, 9 insertions(+), 29 deletions(-) (limited to 'fs/nfs/nfs3proc.c') diff --git a/fs/nfs/nfs3proc.c b/fs/nfs/nfs3proc.c index eac07f2c99dd..c7ca5d70870b 100644 --- a/fs/nfs/nfs3proc.c +++ b/fs/nfs/nfs3proc.c @@ -370,41 +370,21 @@ nfs3_proc_remove(struct inode *dir, struct qstr *name) return status; } -static int -nfs3_proc_unlink_setup(struct rpc_message *msg, struct dentry *dir, struct qstr *name) +static void +nfs3_proc_unlink_setup(struct rpc_message *msg, struct inode *dir) { - struct unlinkxdr { - struct nfs_removeargs arg; - struct nfs_removeres res; - } *ptr; - - ptr = kmalloc(sizeof(*ptr), GFP_KERNEL); - if (!ptr) - return -ENOMEM; - ptr->arg.fh = NFS_FH(dir->d_inode); - ptr->arg.name.name = name->name; - ptr->arg.name.len = name->len; - nfs_fattr_init(&ptr->res.dir_attr); msg->rpc_proc = &nfs3_procedures[NFS3PROC_REMOVE]; - msg->rpc_argp = &ptr->arg; - msg->rpc_resp = &ptr->res; - return 0; } static int -nfs3_proc_unlink_done(struct dentry *dir, struct rpc_task *task) +nfs3_proc_unlink_done(struct rpc_task *task, struct inode *dir) { - struct rpc_message *msg = &task->tk_msg; - struct nfs_fattr *dir_attr; - - if (nfs3_async_handle_jukebox(task, dir->d_inode)) - return 1; - if (msg->rpc_argp) { - dir_attr = &((struct nfs_removeres*)msg->rpc_resp)->dir_attr; - nfs_post_op_update_inode(dir->d_inode, dir_attr); - kfree(msg->rpc_argp); - } - return 0; + struct nfs_removeres *res; + if (nfs3_async_handle_jukebox(task, dir)) + return 0; + res = task->tk_msg.rpc_resp; + nfs_post_op_update_inode(dir, &res->dir_attr); + return 1; } static int -- cgit v1.2.3
