[patch 07/54] fuse: fix mknod of regular file

[Chris Wright]

-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
filesystem.

Thanks to J. Cameijo Cerdeira for the report.

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