fuse: fix permission checking
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 :(( Signed-off-by: Miklos Szeredi <mszeredi@suse.cz> Cc: <stable@kernel.org> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
