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.
To be compitable with the existed format of pGp, the new introduced ones
also use '|' as the separator, then the user tools parsing pGp won't
need to make change, suggested by Matthew. The new information is
tracked onto the end of the existed one.
On example of the output in mm/slub.c as follows,
- Before the patch,
[ 6343.396602] Slab 0x000000004382e02b objects=33 used=3 fp=0x000000009ae06ffc
flags=0x17ffffc0010200(slab|head)
- After the patch,
[ 8838.835456] Slab 0x000000002828b78a objects=33 used=3 fp=0x00000000d04efc88
flags=0x17ffffc0010200(slab|head|node=0|zone=2|lastcpupid=0x1fffff)
Did not review in detail, but LGTM.
Thanks, this will be very helpful!
