bootmem: use kmemleak_free_part_phys in put_page_bootmem
Patch series "Some bugfix about kmemleak", v3.
Some bugfixes for kmemleak and the printed info from debug mode.
This patch (of 7):
Since kmemleak_alloc_phys() rather than kmemleak_alloc() was called from
memblock_alloc_range_nid(), kmemleak_free_part_phys() should be used to
delete kmemleak object in put_page_bootmem(). In debug mode, there are
following warning:
kmemleak: Partially freeing unknown object at 0xffff97345aff7000 (size 4096)
