I will include these in a later update, unless you think they are really urgent and should be added to this one.
Well, I thought worth to mention those patches, but in reality haven't checked if they are applicable to v3.16. It's just I remember "tty: Hold tty_ldisc_lock() during tty_reopen()" was the main fix in the set, as many people suffered from issue under it, so I thought strange that only a side-patch (which can lead to soft lockup, so probably also important) is ported. But I managed to forget that the code has changes since v3.16.
I couldn't see how to apply these to 3.16, so you will need to send me backports if they are needed. They are also missing from 3.18 and 4.4.
Ben.
