From: Jeff Layton <jlayton@redhat.com>
------------------- This is a commit scheduled for the next v2.6.34 longterm release. If you see a problem with using this for longterm, please comment. -------------------
commit 221d1d797202984cb874e3ed9f1388593d34ee22 upstream.
The is_path_accessible check uses a QPathInfo call, which isn't supported by ancient win9x era servers. Fall back to an older SMBQueryInfo call if it fails with the magic error codes.
