Hello,
Page owner tracks a call chain that has allocated a page, this
patch set extends it with a free_pages call chain tracking
functionality.
Page dump, thus, now has the following format:
a) page allocated backtrace
b) page free backtrace
c) backtrace of the path that has trigger bad page
For a quick example of a case when this new b) part can make a
difference please see 0003.
v2:
-- do not add PAGE_OWNER_TRACK_FREE .config -- Joonsoo
-- minor improvements
Sergey Senozhatsky (3):
mm/page_owner: rename page_owner functions
mm/page_owner: rename PAGE_EXT_OWNER flag
mm/page_owner: track page free call chain
