// prune "pruneRows" of type "id" from the buffer.
//
+// This garbage collection task is used to expire log entries. It is called to
+// remove all logs (clear), all UID logs (unprivileged clear), or every
+// 256 or 10% of the total logs (whichever is less) to prune the logs.
+//
+// First there is a prep phase where we discover the reader region lock that
+// acts as a backstop to any pruning activity to stop there and go no further.
+//
+// There are three major pruning loops that follow. All expire from the oldest
+// entries. Since there are multiple log buffers, the Android logging facility
+// will appear to drop entries 'in the middle' when looking at multiple log
+// sources and buffers. This effect is slightly more prominent when we prune
+// the worst offender by logging source. Thus the logs slowly loose content
+// and value as you move back in time. This is preferred since chatty sources
+// invariably move the logs value down faster as less chatty sources would be
+// expired in the noise.
+//
+// The first loop performs blacklisting and worst offender pruning. Falling
+// through when there are no notable worst offenders and have not hit the
+// region lock preventing further worst offender pruning. This loop also looks
+// after managing the chatty log entries and merging to help provide
+// statistical basis for blame. The chatty entries are not a notification of
+// how much logs you may have, but instead represent how much logs you would
+// have had in a virtual log buffer that is extended to cover all the in-memory
+// logs without loss. They last much longer than the represented pruned logs
+// since they get multiplied by the gains in the non-chatty log sources.
+//
+// The second loop get complicated because an algorithm of watermarks and
+// history is maintained to reduce the order and keep processing time
+// down to a minimum at scale. These algorithms can be costly in the face
+// of larger log buffers, or severly limited processing time granted to a
+// background task at lowest priority.
+//
+// This second loop does straight-up expiration from the end of the logs
+// (again, remember for the specified log buffer id) but does some whitelist
+// preservation. Thus whitelist is a Hail Mary low priority, blacklists and
+// spam filtration all take priority. This second loop also checks if a region
+// lock is causing us to buffer too much in the logs to help the reader(s),
+// and will tell the slowest reader thread to skip log entries, and if
+// persistent and hits a further threshold, kill the reader thread.
+//
+// The third thread is optional, and only gets hit if there was a whitelist
+// and more needs to be pruned against the backstop of the region lock.
+//
// mLogElementsLock must be held when this function is called.
