init_peercred() is called in 3 places: 1. socketpair() : both sockets 2. connect() : child socket 3. listen() : listening socket The first two need not hold sk_peer_lock because no one can touch the socket. Let's set cred/pid without holding lock for the two cases and rename the old init_peercred() to update_peercred() to properly reflect the use case.

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 reStructuredText 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.
