SubjectRe: NFS locking bug -- limited mtime resolution means nfs_lock() does not provide coherency guarantee

From the 32-bit storage area currently allocated to i_generation on
the on-disk ext2fs inode (as per Ted's suggestion). With current
disk/computing speeds, you probably don't need the full 32 bits to
offer a reasonable guarantee of inode number uniqueness.

Cheers,
Trond
