This toolset was designed to facilitate the testing, monitoring, and
tracing of various things with virtual memory, pages, and slab objects.
It is an invaluable resource for identifying and analyzing
memory-related issues, such as leaks and bottlenecks, and can greatly
enhance one's understanding of memory utilization within a system.
The mm toolset includes:
- page_owner_sort: userspace helper to sort the output of
/sys/kernel/debug/page_owner, which helps to know who allocates
the page from kernel context
- slabinfo: the tool which gets reports about slabs, for example
show empty slabs, modify of slab debug options at runtime, display
all information about a slabcache
- page-types: a handy tool for querying page flags

[yann.morin.1998@free.fr:
- don't depend on linux, already a patch dependency
- don't set CC: default is based on CROSS_COMPILE
- no need to fully recheck at install time
- move the option for alphabetical ordering
- fix check-package
