      swap: fix shmem swapping when more than 8 areas · 9b15b817
      Hugh Dickins 提交于
      Minchan Kim reports that when a system has many swap areas, and tmpfs
      swaps out to the ninth or more, shmem_getpage_gfp()'s attempts to read
      back the page cannot locate it, and the read fails with -ENOMEM.
      
      Whoops.  Yes, I blindly followed read_swap_header()'s pte_to_swp_entry(
      swp_entry_to_pte()) technique for determining maximum usable swap
      offset, without stopping to realize that that actually depends upon the
      pte swap encoding shifting swap offset to the higher bits and truncating
      it there.  Whereas our radix_tree swap encoding leaves offset in the
      lower bits: it's swap "type" (that is, index of swap area) that was
      truncated.
      
      Fix it by reducing the SWP_TYPE_SHIFT() in swapops.h, and removing the
      broken radix_to_swp_entry(swp_to_radix_entry()) from read_swap_header().
      
      This does not reduce the usable size of a swap area any further, it
      leaves it as claimed when making the original commit: no change from 3.0
      on x86_64, nor on i386 without PAE; but 3.0's 512GB is reduced to 128GB
      per swapfile on i386 with PAE.  It's not a change I would have risked
      five years ago, but with x86_64 supported for ten years, I believe it's
      appropriate now.
      
      Hmm, and what if some architecture implements its swap pte with offset
      encoded below type? That would equally break the maximum usable swap
      offset check.  Happily, they all follow the same tradition of encoding
      offset above type, but I'll prepare a check on that for next.

         of MSRs from the guest.

         were added back in. This resulted in the balloon worker having the wrong
