Subject: nd->inode is not set on the second attempt in path_walk()
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=b306419ae08d9def53f2142a37cc0a58622307a8;p=linux-beck.git

nd->inode is not set on the second attempt in path_walk()

We leave it at whatever it had been pointing to after the
first link_path_walk() had failed with -ESTALE.  Things
do not work well after that...
