Hou Tao says: ==================== From: Hou Tao <houtao1@huawei.com> Hi, The patch set tries to fix the problems found when testing ringbuf by using 4KB and 2GB size. Patch 1 fixes the probe of ring buffer map on host with 64KB page (e.g., an ARM64 host). Patch 2 & 3 fix the overflow of length when mmaping 2GB kernel ringbuf or user ringbuf on libbpf. Patch 4 just reject the reservation with invalid size. Please see individual patch for details. And comments are always welcome. Change Log: v2: * patch 1: use page size instead of adjust_ringbuf_sz(4096) as main_entries (suggested by Stanislav) * patch 2 & 3: use "mmap_sz" instead of "ro_size/wr_size" as name of mmap length (From Andrii) v1: https://lore.kernel.org/bpf/20221111092642.2333724-1-houtao@huaweicloud.com ==================== Signed-off-by: Andrii Nakryiko <andrii@kernel.org> |

README
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.
