cpt-drop-DCACHE_NFSFS_RENAMED-for-all-NFS-dentries-on-kill.patch

   1 cpt: drop DCACHE_NFSFS_RENAMED for all NFS dentries on kill
   2

   5 No need to check for dentry is hashed: things are changing and silly-renamed
   6 dentries are hashed now.
   7 And no need to check for dentry belongs to NFS mount: flag
   8 DCACHE_NFSFS_RENAMED is set only for NFS dentries.
