I've rewritten the commit description to this:

ext4: Properly initialize the buffer_head state

From: "Aneesh Kumar K.V" <aneesh.kumar@...ux.vnet.ibm.com>

These struct buffer_heads are allocated on the stack (and hence are
initialized with stack garbage).  They are only used to call a
get_blocks() function, so that's mostly OK, but b_state must be
initialized to be 0.
