fuse: fix permission checking
[upstream commit 1a823ac9ff09cbdf39201df37b7ede1f9395de83]
I added a nasty local variable shadowing bug to fuse in 2.6.24, with the
result, that the 'default_permissions' mount option is basically ignored.
How did this happen?
- old err declaration in inner scope
- new err getting declared in outer scope
- 'return err' from inner scope getting removed
- old declaration not being noticed
-Wshadow would have saved us, but it doesn't seem practical for
the kernel :(
More testing would have also saved us :((
