| |
2.6.38-stable review patch. If anyone has any objections, please let us know.
------------------
From: Jeff Layton <jlayton@redhat.com>
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.
