2012-08-06mISDN: Bugfix for layer2 fixed TEI modeKarsten Keil1-1/+1
If a fixed TEI is used, the initial state of the layer 2 statmachine need to be 4 (TEI assigned). This was true only for Point to Point connections, but not for the other fixed TEIs. It was not found before, because usually only the TEI 0 is used as fixed TEI for PtP mode, but if you try X31 packet mode connections with SAPI 16, TEI 1, it did fail.

There's a bug that causes the rate scaling to get stuck when it has to use single-stream rates with a peer that can do GF and SGI; the two are incompatible so we can't use them together, but that causes the algorithm to not work at all, it always rejects updates.

2012-08-04vfs: kill write_super and sync_supersArtem Bityutskiy5-97/+0
Finally we can kill the 'sync_supers' kernel thread along with the '->write_super()' superblock operation because all the users are gone. Now every file-system is supposed to self-manage own superblock and its dirty state. The nice thing about killing this thread is that it improves power management. Indeed, 'sync_supers' is a source of monotonic system wake-ups - it woke up every 5 seconds no matter what - even if there were no dirty superblocks and even if there were no file-systems using this service (e.g., btrfs and journalled ext4 do not need it). So it was wasting power most of the time. And because the thread was in the core of the kernel, all systems had to have it. So I am quite happy to make it go away. Interestingly, this thread is a left-over from the pdflush kernel thread which was a self-forking kernel thread responsible for all the write-back in old Linux kernels. It was turned into per-block device BDI threads, and 'sync_supers' was a left-over. Thus, R.I.P, pdflush as well.
