mm: page_owner: fix wrong information in dump_page_owner
With commit ea4b5b3 ("mm,page_owner: update metadata for tail pages"), new API __update_page_owner_handle was introduced and arguemnt was passed in wrong order from __set_page_owner and thus page_owner is giving wrong data. [ 15.982420] page last allocated via order 0, migratetype Unmovable, gfp_mask 0xcc0(GFP_KERNEL), pid 80, tgid -1210279584 (insmod), ts 80, free_ts 0 Fixing the same. Correct output: [ 14.556482] page last allocated via order 0, migratetype Unmovable, gfp_mask 0xcc0(GFP_KERNEL), pid 80, tgid 80 (insmod), ts 14552004992, free_ts 0 Link: https://lkml.kernel.org/r/20240424111838.3782931-1-hariom1.p@samsung.com Fixes: ea4b5b3 ("mm,page_owner: update metadata for tail pages") Signed-off-by: Maninder Singh <maninder1.s@samsung.com> Signed-off-by: Hariom Panthi <hariom1.p@samsung.com> Acked-by: Oscar Salvador <osalvador@suse.de> Cc: Christoph Hellwig <hch@infradead.org> Cc: Lorenzo Stoakes <lstoakes@gmail.com> Cc: Rohit Thapliyal <r.thapliyal@samsung.com> Cc: Uladzislau Rezki (Sony) <urezki@gmail.com> Cc: Vlastimil Babka <vbabka@suse.cz> Signed-off-by: Andrew Morton <akpm@linux-foundation.org>
