Linus Torvalds 34d5a4b336 Fix for yet another subtle futex issue. The futex code used ihold() to
prevent inodes from vanishing, but ihold() does not guarantee inode
 persistence. Replace the inode pointer with a per boot, machine wide,
 unique inode identifier. The second commit fixes the breakage of the hash
 mechanism whihc causes a 100% performance regression.
