Its filename is mm-hmm-hmm_pfns_bad-was-accessing-wrong-struct.patch This patch should soon appear at http://ozlabs.org/~akpm/mmots/broken-out/mm-hmm-hmm_pfns_bad-was-accessing-wrong-struct.patch and later at http://ozlabs.org/~akpm/mmotm/broken-out/mm-hmm-hmm_pfns_bad-was-accessing-wrong-struct.patch Before you just go and hit "reply", please: a) Consider who else should be cc'ed b) Prefer to cc a suitable mailing list as well c) Ideally: find the original patch on the mailing list and do a reply-to-all to that, adding suitable additional cc's *** Remember to use Documentation/process/submit-checklist.rst when testing your code *** The -mm tree is included into linux-next and is updated there every 3-4 working days ------------------------------------------------------ From: Jérôme Glisse Subject: mm/hmm: hmm_pfns_bad() was accessing wrong struct The private field of mm_walk struct point to an hmm_vma_walk struct and not to the hmm_range struct desired. Fix to get proper struct pointer.
