-stable review patch. If anyone has any objections, please let us know.
---------------------
From: Miklos Szeredi <[email protected]>
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.
