ext3_msg() takes the printk prefix as the second parameter and the
format string as the third parameter. Two callers of ext3_msg omit the
prefix and pass the format string as the second parameter and the first
parameter to the format string as the third parameter. In both cases
this string comes from an arbitrary source. Which means the string may
contain format string characters, which will
lead to undefined and potentially harmful behavior.
The issue was introduced in commit 4cf46b67eb("ext3: Unify log messages
in ext3") and is fixed by this patch.

This is the first NFC pull request for 3.10.
The 2 features we have with this one are:
- An LLCP Service Name Lookup (SNL) netlink interface for querying LLCP
service availability from user space.
Along the way, Thierry also improved the existing SNL interface for
aggregating SNL responses.
- An initial LLCP socket options implementation, for setting the Receive

This is need for the LLCP validation tests.

jbd2: fix use after free in jbd2_journal_dirty_metadata()
jbd2_journal_dirty_metadata() didn't get a reference to journal_head it
was working with. This is OK in most of the cases since the journal head
should be attached to a transaction but in rare occasions when we are
journalling data, __ext4_journalled_writepage() can race with
jbd2_journal_invalidatepage() stripping buffers from a page and thus
journal head can be freed under hands of jbd2_journal_dirty_metadata().
Fix the problem by getting own journal head reference in
jbd2_journal_dirty_metadata() (and also in jbd2_journal_set_triggers()
which can possibly have the same issue).
