4.14-stable review patch. If anyone has any objections, please let me know.FYI, this broke kdump, or rather the makedumpfile part thereof. �Forward looking wreckage is par for the kdump course, but...Is it also broken in Linus's tree with this patch? Or is there an add-on patch that I should apply to 4.14 to resolve this issue there?This one http://lkml.kernel.org/r/1513932498-20350-1-git-send-email-bhe@redhat.com I guess.That won't unbreak kdump, else master wouldn't be broken. �I don't care deeply, or know if anyone else does, I'm just reporting it because I met it and chased it down.OK, I didn't notice that d8cfbbfa0f7 ("mm/sparse.c: wrong allocation for mem_section") made it in after rc6. I am still wondering why 83e3c48729 ("mm/sparsemem: Allocate mem_section at runtime for CONFIG_SPARSEMEM_EXTREME=y") made it into the stable tree in the first place.It was part of the prep for the KTPI code from what I can tell. If you think it should be reverted, just let me know and I'll be glad to do so.No preference here. �I have to patch master regardless if I want kdump to work while I patiently wait for userspace to get fixed up (either that or use time I don't have to go fix it up myself).
I'll stay "bug compatible" for the time being. If you do fix this up, can you add a cc: stable tag in your patch so I can pick it up when it gets merged? thanks, greg k-h -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
