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 <ego@in.ibm.com> Signed-off-by: Aneesh Kumar K.V <aneesh.kumar@linux.vnet.ibm.com> Signed-off-by: Eric Van Hensbergen <ericvh@gmail.com>
