Subject[PATCH 0/5] mm/hmm: HMM documentation updates and code fixes
From: Ralph Campbell <>

I hit a use after free bug in hmm_free() with KASAN and then couldn't
stop myself from cleaning up a bunch of documentation and coding style
changes. So the first two patches are clean ups, the last three are
the fixes.

Ralph Campbell (5):
mm/hmm: Update HMM documentation
mm/hmm: Clean up some coding style and comments
mm/hmm: Use mm_get_hmm() in hmm_range_register()
mm/hmm: hmm_vma_fault() doesn't always call hmm_range_unregister()
mm/hmm: Fix mm stale reference use in hmm_free()
