3.2.48-rc1 review patch. If anyone has any objections, please let me know.
------------------
From: Dave Chiluk <chiluk@xxxxxxxxxxxxx>
commit 698b8223631472bf982ed570b0812faa61955683 upstream.
1d2ef5901483004d74947bbf78d5146c24038fe7 caused a regression in ncpfs such that
directories could no longer be removed. This was because ncp_rmdir checked
to see if a dentry could be unhashed before allowing it to be removed. Since
1d2ef5901483004d74947bbf78d5146c24038fe7 introduced a change that incremented
dentry->d_count causing it to always be greater than 1 unhash would always
fail. Thus causing the error path in ncp_rmdir to always be taken. Removing
this error path is safe as unhashing is still accomplished by calls to dput
from vfs_rmdir.
