Subject: [PATCH 0/2] mm: improve the output of print_page_info()
Date: Fri, 15 Jan 2021 14:13:47 +0800 [thread overview]
Message-ID: <20210115061349.67386-1-laoar.shao@gmail.com> (raw)
Before that patchset, the output of print_page_info() is
[ 6155.716018] INFO: Slab 0x000000004027dd4f objects=33 used=3 fp=0x000000008cd1579c flags=0x17ffffc0010200
While after it, the output is
[ 8843.757770] INFO: Slab 0x00000000f0e98335 objects=33 used=3 fp=0x00000000b643c7d8 flags=0x10200(slab|head)
The new one is more friendly and human readable.
