commit: 221d1d797202984cb874e3ed9f1388593d34ee22 From: Jeff Layton <[email protected]> Date: Tue, 17 May 2011 06:40:30 -0400 Subject: [PATCH] cifs: add fallback in is_path_accessible for old servers
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.
