[Andrew Morton <akpm@linux-foundation.org>]

The patch titled
     Subject: drivers/base/node: rename register_memory_blocks_under_node() and remove context argument
has been added to the -mm mm-new branch.  Its filename is
     drivers-base-node-rename-register_memory_blocks_under_node-and-remove-context-argument.patch

This patch will shortly appear at
     https://git.kernel.org/pub/scm/linux/kernel/git/akpm/25-new.git/tree/patches/drivers-base-node-rename-register_memory_blocks_under_node-and-remove-context-argument.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
review feedback and post updated versions to replace or incrementally
fixup patches in mm-new.

Subject: drivers/base/node: rename register_memory_blocks_under_node() and remove context argument
Date: Wed, 28 May 2025 12:18:03 -0500

The function register_memory_blocks_under_node() is now only called from
the memory hotplug path, as register_memory_blocks_under_node_early()
handles registration during early boot.  Therefore, the context argument
used to differentiate between early boot and hotplug is no longer needed
and was removed.

Since the function is only called from the hotplug path, we renamed
register_memory_blocks_under_node() to
register_memory_blocks_under_node_hotplug()
