JIRA: https://issues.redhat.com/browse/RHEL-102164 Conflicts: context different due to missing 6bf9b5b40af3 "mm: alloc_pages_bulk: rename API" commit ed603bcf4feac05df937bf78bc7feb75f988a971 Author: Chuck Lever <chuck.lever@oracle.com> Date: Mon, 28 Apr 2025 15:36:52 -0400 sunrpc: Replace the rq_pages array with dynamically-allocated memory As a step towards making NFSD's maximum rsize and wsize variable at run-time, replace the fixed-size rq_vec[] array in struct svc_rqst with a chunk of dynamically-allocated memory. On a system with 8-byte pointers and 4KB pages, pahole reports that the rq_pages[] array is 2080 bytes. This patch replaces that with a single 8-byte pointer field.

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.
