Subject: [PATCH 29/29] s3:notifyd: Use a watcher per db record
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
This fixes a O(n²) performance regression in notifyd. The problem was
that we had a watcher per notify instance. This changes the code to have
a watcher per notify db entry.
