From: Chris Wright
Date: Fri Jun 08 2007 - 03:22:46 EST

-stable review patch. If anyone has any objections, please let us know.

From: Miklos Szeredi <mszeredi@xxxxxxx>

The wrong lookup flag was tested in ->create() causing havoc (error or
Oops) when a regular file was created with mknod() in a fuse

Thanks to J. Cameijo Cerdeira for the report.

Kernels 2.6.18 onward are affected. Please apply to -stable as well.
