       "A couple of fixes for bootconfig.
      
        Masami discovered two bugs which this fixes and he added tests to
        cover these issues.
      
         - Fix a bug that breaks bootconfig tree nodes
      
         - Fix a bug that does not truncate whitespace properly
      
         - Add tests to cover the above two cases"

      Pull device mapper fixes from Mike Snitzer:
      
       - DM core fix for incorrect double bio splitting. Keep "fixing" this
         because past attempts didn't fully appreciate the liability relative
         to recursive bio splitting. This fix limits DM's bio splitting to a
         single method and does _not_ use blk_queue_split() for normal IO.
      
       - DM crypt Documentation updates for features added during 5.9 merge.

      mm: move the copy_one_pte() pte_present check into the caller · 79a1971c
      Linus Torvalds authored
      This completes the split of the non-present and present pte cases by
      moving the check for the source pte being present into the single
      caller, which also means that we clearly separate out the very different
      return value case for a non-present pte.
      
      The present pte case currently always succeeds.
      
      This is a pure code re-organization with no semantic change: the intent
      is to make it much easier to add a new return case to the present pte
      case for when we do early COW at page table copy time.
      
      This was split out from the previous commit simply to make it easy to
      visually see that there were no semantic changes from this code
      re-organization.

      mm: split out the non-present case from copy_one_pte() · df3a57d1
      Linus Torvalds authored
      This is a purely mechanical split of the copy_one_pte() function.  It's
      not immediately obvious when looking at the diff because of the
      indentation change, but the way to see what is going on in this commit
      is to use the "-w" flag to not show pure whitespace changes, and you see
      how the first part of copy_one_pte() is simply lifted out into a
      separate function.
      
      And since the non-present case is marked unlikely, don't make the new
      function be inlined.  Not that gcc really seems to care, since it looks
      like it will inline it anyway due to the whole "single callsite for
      static function" logic.  In fact, code generation with the function
      split is almost identical to before.  But not marking it inline is the
      right thing to do.
      
      This is pure prep-work and cleanup for subsequent changes.
