mainlining shenanigans
af34983e83
For user namespace support, call vfs functions with struct user_namespace got from struct path. This patch have been tested mannually as below. Create an id-mapped mount using the mount-idmapped utility (https://github.com/brauner/mount-idmapped). $ mount-idmapped --map-mount b:1003:1002:1 /home/foo <EXPORT DIR>/foo (the user, "foo" is 1003, and the user "bar" is 1002). And mount the export directory using cifs with the user, "bar". succeed to create/delete/stat/read/write files and directory in the <EXPORT DIR>/foo. But fail with a bind mount for /home/foo.

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.
