The UserSliceReader::read_all function is currently restricted to use only Vec with the kmalloc allocator. However, there is no reason for this limitation. This patch generalizes the function to accept any Vec regardless of the allocator used. There's a use-case for a KVVec in Binder to avoid maximum sizes for a certain array.

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.
