Greg Kroah-Hartman has announced the release of the 3.0.51 (diffs), 3.4.18
(diffs), and 3.6.6 (diffs) stable kernels. They contain fixes
throughout the tree and users should upgrade. The latter two (3.4.18,
3.6.6) contain the fix for the ext4 corruption
problem that initially looked much worse than it turned out to be.
