Xuewei Niu says: ==================== vsock: Introduce SIOCINQ ioctl support Introduce SIOCINQ ioctl support for vsock, indicating the length of unread bytes. Similar with SIOCOUTQ ioctl, the information is transport-dependent. The first patch adds SIOCINQ ioctl support in AF_VSOCK. Thanks to @dexuan, the second patch is to fix the issue where hyper-v `hvs_stream_has_data()` doesn't return the readable bytes. The third patch wraps the ioctl into `ioctl_int()`, which implements a retry mechanism to prevent immediate failure. The last one adds two test cases to check the functionality. The changes have been tested, and the results are as expected. ==================== Link: https://patch.msgid.link/20250708-siocinq-v6-0-3775f9a9e359@antgroup.com Signed-off-by: Jakub Kicinski <kuba@kernel.org> |

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.
