       "Things seem to be settling down as far as networking is concerned,
        let's hope this trend continues...
      
         1) Add iov_iter_revert() and use it to fix the behavior of

      Netfilter fixes for net
      
      The following patchset contains Netfilter fixes for your net tree,

         from Gao feng.

      5) Fix missing read_lock_bh when iterating over list of device addresses
         from TPROXY and redirect, also from Liping.
      
      6) Fix crash when trying to dump expectations from conntrack with no
         helper via ctnetlink, from Liping.
      
      7) Missing RCU protection to expecation list update given ctnetlink
         iterates over the list under rcu read lock side, from Liping too.
      
      8) Don't dump autogenerated seed in nft_hash to userspace, this is
         very confusing to the user, again from Liping.

        The presence of 'thp: reduce indentation level in change_huge_pmd()'
        is unfortunate. But the patchset had been decently reviewed and tested
        before we decided it was needed in -stable and I felt it best not to
        churn things at the last minute"

      zsmalloc: expand class bit · 85d492f2
      Minchan Kim authored
      Now 64K page system, zsamlloc has 257 classes so 8 class bit is not
      enough.  With that, it corrupts the system when zsmalloc stores
      65536byte data(ie, index number 256) so that this patch increases class
      bit for simple fix for stable backport.  We should clean up this mess
      soon.

      zram: do not use copy_page with non-page aligned address · d72e9a7a
      Minchan Kim authored
      The copy_page is optimized memcpy for page-alinged address.  If it is
      used with non-page aligned address, it can corrupt memory which means
      system corruption.  With zram, it can happen with
      
      1. 64K architecture
      2. partial IO
      3. slub debug
      
      Partial IO need to allocate a page and zram allocates it via kmalloc.
      With slub debug, kmalloc(PAGE_SIZE) doesn't return page-size aligned
      address.  And finally, copy_page(mem, cmem) corrupts memory.
      
      So, this patch changes it to memcpy.
      
      Actuaully, we don't need to change zram_bvec_write part because zsmalloc
      returns page-aligned address in case of PAGE_SIZE class but it's not
      good to rely on the internal of zsmalloc.
      
      Note:
       When this patch is merged to stable, clear_page should be fixed, too.
       Unfortunately, recent zram removes it by "same page merge" feature so
       it's hard to backport this patch to -stable tree.
      
      I will handle it when I receive the mail from stable tree maintainer to
      merge this patch to backport.
