Frederick Lawler 401e64b3a4 bpf-lsm: Make bpf_lsm_userns_create() sleepable
Users may want to audit calls to security_create_user_ns() and access
user space memory. Also create_user_ns() runs without
pagefault_disabled(). Therefore, make bpf_lsm_userns_create() sleepable
for mandatory access control policies.

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.
