Changelog
v2: * Fixed the inconsistent behavior by not aborting !vma_migratable()
immediately by a separate patch (patch 1/2), and this is also
the
preparation for patch 2/2. For the details please see the commit
log. Per Vlastimil.
* Not abort immediately if unmovable page is met. This should
handle
non-LRU movable pages and temporary off-LRU pages more friendly.
Per Vlastimil and Michal Hocko.
Yang Shi (2):
mm: mempolicy: make the behavior consistent when
MPOL_MF_MOVE* and MPOL_MF_STRICT were specified
mm: mempolicy: handle vma with unmovable pages mapped
correctly in mbind
I'm seeing no evidence of review on these two. Could we please take a
look? 2/2 fixes a kernel crash so let's please also think about the
-stable situation.
Thanks for following up this. It seems I have a few patches stalled
due to lack of review.
BTW, this would not crash post-4.9 kernel since that BUG_ON had been
removed. But, that behavior is definitely problematic as the commit
log elaborated.
I have a note here that Vlastimil had an issue with [1/2] but I seem to
hae misplaced that email :(
Vlastimil suggested something for v1, then I think his concern and
suggestion have been solved in this version. But, the review was stalled.
