The journal replay code starts by finding something that looks like a valid journal entry, then it does a binary search over the unchecked region of the journal for the journal entries with the highest sequence numbers. Trouble is, the logic was wrong - journal_read_bucket() returns true if it found journal entries we need, but if the range of journal entries we're looking for loops around the end of the journal - in that case journal_read_bucket() could return true when it hadn't found the highest sequence number we'd seen yet, and in that case the binary search did the wrong thing. Whoops. Signed-off-by: Kent Overstreet <kmo@daterainc.com> Cc: linux-stable <stable@vger.kernel.org> # >= v3.10
