Linux kernel source tree
b76f1467dc
We can re-order some struct members and take u32 credits outside of the
pointer sandwich and also for the last_dependency member we can get away
with an unsigned int since for dependency we use xa_limit_32b.
Pahole report before:
/* size: 160, cachelines: 3, members: 14 */
/* sum members: 156, holes: 1, sum holes: 4 */
/* last cacheline: 32 bytes */
And after:
/* size: 152, cachelines: 3, members: 14 */
/* last cacheline: 24 bytes */

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.
