Subject: [merged mm-stable] mm-hugetlb-move-hugetlb_sysfs_initialized-into-hugetlb_register_all_nodes.patch removed from -mm tree
Date: Sat, 24 Oct 2026 02:01:09 -0700	[thread overview]
Message-ID: <20261024090109.DCC1C1F01828@smtp.kernel.org> (raw)


The quilt patch titled
     Subject: mm/hugetlb: move hugetlb_sysfs_initialized into hugetlb_register_all_nodes()
has been removed from the -mm tree.  Its filename was
     mm-hugetlb-move-hugetlb_sysfs_initialized-into-hugetlb_register_all_nodes.patch

This patch was dropped because it was merged into the mm-stable branch
of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm

Subject: mm/hugetlb: move hugetlb_sysfs_initialized into hugetlb_register_all_nodes()
Date: Fri,  9 Oct 2026 22:20:10 +0800

hugetlb_sysfs_init() guards the "hugetlb_sysfs_initialized = true"
assignment with an #ifdef CONFIG_NUMA block, while the following
hugetlb_register_all_nodes() call is left unguarded and relies on the
empty !CONFIG_NUMA stub.

Move the assignment into the NUMA version of hugetlb_register_all_nodes(),
before it registers the online nodes, so the #ifdef in
hugetlb_sysfs_init() can go away.  Keep the !CONFIG_NUMA stub, so the call
site is unconditional in both configurations.

No functional change; this is an #ifdef cleanup.
