From f952e137849253c0584a60cc2d73a220d9a091f8 Mon Sep 17 00:00:00 2001 From: Jeff Layton Date: Fri, 6 Jul 2012 07:09:42 -0400 Subject: cifs: always update the inode cache with the results from a FIND_* commit cd60042cc1392e79410dc8de9e9c1abb38a29e57 upstream. When we get back a FIND_FIRST/NEXT result, we have some info about the dentry that we use to instantiate a new inode. We were ignoring and discarding that info when we had an existing dentry in the cache. Fix this by updating the inode in place when we find an existing dentry and the uniqueid is the same.
