Subject[RFC 00/11] mm: debug: formatting memory management structs
Date
This patch series adds knowledge about various memory management structures
to the standard print functions.

In essence, it allows us to easily print those structures:

printk("%pZp %pZm %pZv", page, mm, vma);

This allows us to customize output when hitting bugs even further, thus
we introduce VM_BUG() which allows printing anything when hitting a bug
rather than just a single piece of information.

This also means we can get rid of VM_BUG_ON_* since they're now nothing
more than a format string.

Sasha Levin (11):
mm: debug: format flags in a buffer
mm: debug: deal with a new family of MM pointers
mm: debug: dump VMA into a string rather than directly on screen
mm: debug: dump struct MM into a string rather than directly on
screen
mm: debug: dump page into a string rather than directly on screen
mm: debug: clean unused code
mm: debug: VM_BUG()
mm: debug: kill VM_BUG_ON_PAGE
mm: debug: kill VM_BUG_ON_VMA
mm: debug: kill VM_BUG_ON_MM
mm: debug: use VM_BUG() to help with debug output
