Inline copy_from_user() and copy_to_user(). With the shortened inline assemblies of raw_copy_to_user() and raw_copy_from_user() the additional kernel text size is acceptable, considering that this avoids function calls on hot paths. This increases the kernel text size by ~90kb (defconfig, gcc 14.2.0): add/remove: 13/4 grow/shrink: 650/14 up/down: 93484/-3254 (90230) Signed-off-by: Heiko Carstens <hca@linux.ibm.com> Signed-off-by: Vasily Gorbik <gor@linux.ibm.com>
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.
