| |
-stable review patch. If anyone has any objections, please let us know.
------------------ From: Badari Pulavarty <pbadari@us.ibm.com>
For files other than IFREG, nobh option doesn't make sense. Modifications to them are journalled and needs buffer heads to do that. Without this patch, we get kernel oops in page_buffers().
