Currently the pGp only shows the names of page flags, rather than the full information including section, node, zone, last cpupid and kasan tag. While it is not easy to parse these information manually because there're so many flavors. Let's interpret them in pGp as well. This patchset also includes some code cleanup in mm/slub.c. Below is the example of the output in mm/slub.c. - Before the patchset [ 6155.716018] INFO: Slab 0x000000004027dd4f objects=33 used=3 fp=0x000000008cd1579c flags=0x17ffffc0010200 - After the patchset [ 6315.235783] ERR: Slab 0x000000006d1133b9 objects=33 used=3 fp=0x000000006d0779d1 flags=0x17ffffc0010200(Node 0x0,Zone 0x2,Lastcpupid 0x1fffff,slab|head) Yafang Shao (3): mm, slub: use pGp to print page flags mm, slub: don't combine pr_err with INFO printk: dump full information of page flags in pGp lib/vsprintf.c | 42 +++++++++++++++++++++++++++++++++++++++++- mm/slub.c | 13 +++++++------ 2 files changed, 48 insertions(+), 7 deletions(-) -- 2.17.1
