New Revision: 346094
URL: https://svnweb.freebsd.org/changeset/base/346094
Log:
Fix a small bug in the tcp_log_id where the bucket
was unlocked and yet the bucket-unlock flag was not
changed to false. This can cause a panic if INVARIANTS
is on and we go through the right path (though rare).
This fixes the correct bug :)
