Its filename was mm-page_owner-move-free_ts_nsec-output-to-free-section-in-__dump_page_owner.patch This patch was dropped because an updated version will be issued ------------------------------------------------------ From: Ye Liu Subject: mm/page_owner: move free_ts_nsec output to free section in __dump_page_owner() Date: Tue, 23 Jun 2026 14:52:30 +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.
