[merged mm-stable] hugetlbfs-fix-stale-comment-in-hugetlbfs_file_mmap.patch removed from -mm tree

[Andrew Morton]

The quilt patch titled
     Subject: hugetlbfs: fix stale comment in hugetlbfs_file_mmap()
has been removed from the -mm tree.  Its filename was
     hugetlbfs-fix-stale-comment-in-hugetlbfs_file_mmap.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: hugetlbfs: fix stale comment in hugetlbfs_file_mmap()
Date: Wed, 23 Sep 2026 10:28:58 +0800

The comment above the VMA flag setup in hugetlbfs_file_mmap() says the VMA
address alignment has already been checked by prepare_hugepage_range(). 
That function no longer exists: it was removed by commit eff41389d824
("mm/hugetlb: remove prepare_hugepage_range()"), and the check now lives
in hugetlb_get_unmapped_area().

The comment also mentions ia64, which was removed from the tree by commit
cf8e8658100d ("arch: Remove Itanium (IA-64) architecture").

Point the comment at the current function and drop the ia64 reference. 
The rest of the comment, which tells future edits to add any error return
only after VM_HUGETLB has been set, is still accurate and is left
untouched.

No functional change.
