[merged mm-stable] mm-page_owner-move-free_ts_nsec-output-to-free-section-in-__dump_page_owner.patch removed from -mm tree

[Andrew Morton]

The quilt patch titled
     Subject: mm/page_owner: move free_ts_nsec output to free section in __dump_page_owner()
has been removed from the -mm tree.  Its filename was
     mm-page_owner-move-free_ts_nsec-output-to-free-section-in-__dump_page_owner.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/page_owner: move free_ts_nsec output to free section in __dump_page_owner()
Date: Tue, 14 Jul 2026 09:51:05 +0800

The free_ts_nsec field is a free-event timestamp, but it was printed in
the allocation summary line alongside ts_nsec (allocation time).  Move it
to the free section where it logically belongs, together with free_pid and
free_tgid.  This also makes __dump_page_owner() consistent with
print_page_owner(), which only prints ts_nsec in the allocation summary.

The output now groups all free-related information (pid, tgid, timestamp,
stack trace) in one place.

No functional change except output formatting.
