The patch titled
     Subject: vmalloc: update __vmalloc_node_noprof() documentation
has been added to the -mm mm-new branch.  Its filename is
     vmalloc-update-__vmalloc_node_noprof-documentation.patch

This patch will shortly appear at
     https://git.kernel.org/pub/scm/linux/kernel/git/akpm/25-new.git/tree/patches/vmalloc-update-__vmalloc_node_noprof-documentation.patch

This patch will later appear in the mm-new branch at
    git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm

Note, mm-new is a provisional staging ground for work-in-progress
patches, and acceptance into mm-new is a notification for others take
notice and to finish up reviews.  Please do not hesitate to respond to

Subject: vmalloc: update __vmalloc_node_noprof() documentation
Date: Mon, 13 Oct 2025 19:42:22 +0200

The kernel-doc for __vmalloc_node_noprof() incorrectly states that
__GFP_NOFAIL reclaim modifier is not supported.  In fact it has been
supported since commit 9376130c390a ("mm/vmalloc: add support for
__GFP_NOFAIL").

To avoid duplication and future drift, point this helper's doc to
__vmalloc_node_range_noprof() for details and the full description.
