commit 01bfe5e8e428b475982a98a46cca5755726f3f7f upstream.
This reverts commit b166a20b07382b8bc1dcee2a448715c9c2c81b5b.
This one has to be reverted as it introduced a dead lock, as
syzbot reported:
CPU0 CPU1
---- ----
lock(&net->sctp.addr_wq_lock);
lock(slock-AF_INET6);
lock(&net->sctp.addr_wq_lock);
lock(slock-AF_INET6);
CPU0 is the thread of sctp_addr_wq_timeout_handler(), and CPU1
is that of sctp_close().
The original issue this commit fixed will be fixed in the next
patch.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
