Miklos Szeredi 9c8ef5614d [PATCH] fuse: scramble lock owner ID ... VFS uses current->files pointer as lock owner ID, and it wouldn't be prudent to expose this value to userspace. So scramble it with XTEA using a per connection random key, known only to the kernel. Only one direction needs to be implemented, since the ID is never sent in the reverse direction. The XTEA algorithm is implemented inline since it's simple enough to do so, and this adds less complexity than if the crypto API were used. Thanks to Jesper Juhl for the idea.
