This is an automated email from the git hooks/post-receive script. It was
generated because a ref change was pushed to the repository containing
the project "UNNAMED PROJECT".

The branch, jerlbeck/wip/pdch-alloc has been updated

This update added new revisions after undoing existing revisions.  That is
to say, the old revision is not a strict subset of the new revision.  This
situation occurs when you --force push a change and generate a repository
containing something like this:

 * -- * -- B -- O -- O -- O (6b36049b1adc63886cbb9c4b51185caaba1c675d)
            \
             N -- N -- N (7a4bd9661bd5b5297132ea55c16cd8a5248cb693)

When this happens we assume that you've already had alert emails for all
of the O revisions, and so we here report only the revisions in the N
branch from the common base, B.

Those revisions listed above that are new to this repository have
not appeared on any other notification email; so we list those
revisions in full, below.

    alloc: Optionally enforce first common TS in find_multi_slots (TODO)
    
    TODO:
    
    - This isn't probably triggered at all currently, so this commit
      can possibly be dropped

commit 66ba0844be5058032cb31c6ee3e31428417b171f
Author: Jacob Erlbeck <jerlbeck at sysmocom.de>
Date:   Tue Jul 21 17:25:52 2015 +0200

    bssgp: Use measured leak rate for flow control (EXPERIMENTAL)
    
    THIS IS EXPERIMENTAL, DO NOT USE IN PRODUCTION
    
    The leak rate sent to the SGSN does not reflect the current CS level,
    lost frames, and control message overhead.
    
    Use the ratio between sent blocks and successfully received bytes to
    derive the net leak rate.
    
    TODO:
    - The values are not stable, possibly resulting from interference
      with the sampling rate or from the interval between send and
      receive if they fall into different sampling intervals.
    - Perhaps the rate can be computed from sent data bytes / sent data
      frames or from the average packet size and the global nack rate.
