[PATCH] Fix oops in ufs_fill_super at mount time
There's a lack of parenthesis in fs/ufs/utils.h, so instead of the 512th byte of buffer, the usb2 pointer will point to the nth structure of type ufs_super_block_second. This can cause a mount-time oops if you're unlucky (especially with DEBUG_PAGEALLOC, which is how Alexey Dobriyan saw this problem) Signed-off-by: Evgeniy Dushistov <dushistov@mail.ru> Acked-by: Alexey Dobriyan <adobriyan@gmail.com> Signed-off-by: Linus Torvalds <torvalds@osdl.org> Signed-off-by: Chris Wright <chrisw@sous-sol.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
