From 85e0df240e9376ff58eb1a50d9854f5f176dd297 Mon Sep 17 00:00:00 2001 From: "Aneesh Kumar K.V" Date: Fri, 14 May 2010 13:04:39 +0000 Subject: [PATCH] fs/9p: Make sure we properly instantiate dentry. For lookup if we get ENOENT error from the server we still instantiate the dentry. We need to make sure we have dentry operations set in that case so that a later dput on the dentry does the expected. Without the patch we get the below error #ln -sf abc abclink ln: creating symbolic link `abclink': No such file or directory Now on the host do $ touch abclink Guest now gives ENOENT error. # ls ls: cannot access abclink: No such file or directory Debugged-by:Gautham R Shenoy Signed-off-by: Aneesh Kumar K.V Signed-off-by: Eric Van Hensbergen --- fs/9p/vfs_inode.c | 7 ++++--- 1 file changed, 4 insertions(+), 3 deletions(-) diff --git a/fs/9p/vfs_inode.c b/fs/9p/vfs_inode.c index de9a39590b70..b44c99979143 100644 --- a/fs/9p/vfs_inode.c +++ b/fs/9p/vfs_inode.c @@ -697,8 +697,8 @@ static struct dentry *v9fs_vfs_lookup(struct inode *dir, struct dentry *dentry, if (IS_ERR(fid)) { result = PTR_ERR(fid); if (result == -ENOENT) { - d_add(dentry, NULL); - return NULL; + inode = NULL; + goto inst_out; } return ERR_PTR(result); @@ -715,7 +715,8 @@ static struct dentry *v9fs_vfs_lookup(struct inode *dir, struct dentry *dentry, if (result < 0) goto error; - if ((fid->qid.version) && (v9ses->cache)) +inst_out: + if (v9ses->cache) dentry->d_op = &v9fs_cached_dentry_operations; else dentry->d_op = &v9fs_dentry_operations; -- 2.30.2
