      The root cause is that erofs_workgroup_unfreeze() doesn't reset to

      before freeing.
      
      Since UP platforms are quite rare now, such path becomes unnecessary.
      Let's drop such specific-designed path directly instead.

      erofs: avoid the potentially wrong m_plen for big pcluster · ea0b7b0d
      Yue Hu authored
      Actually, 'compressedlcs' stores compressed block count rather than
      lcluster count. Therefore, the number of bits for shifting the count
      should be 'LOG_BLOCK_SIZE' rather than 'lclusterbits' although current
      lcluster size is 4K.
      
      The value of 'm_plen' will be wrong once we enable the non 4K-sized
      lcluster.

      Makefile.extrawarn: re-enable -Wformat for clang; take 2 · b0839b28
      Nick Desaulniers authored
      -Wformat was recently re-enabled for builds with clang, then quickly
      re-disabled, due to concerns stemming from the frequency of default
      argument promotion related warning instances.
      
      commit 258fafcd ("Makefile.extrawarn: re-enable -Wformat for clang")
      commit 21f9c8a1 ("Revert "Makefile.extrawarn: re-enable -Wformat for clang"")
      
      ISO WG14 has ratified N2562 to address default argument promotion
      explicitly for printf, as part of the upcoming ISO C2X standard.
      
      The behavior of clang was changed in clang-16 to not warn for the cited
      cases in all language modes.
      
      Add a version check, so that users of clang-16 now get the full effect
      of -Wformat. For older clang versions, re-enable flags under the
      -Wformat group that way users still get some useful checks related to
      format strings, without noisy default argument promotion warnings. I
      intentionally omitted -Wformat-y2k and -Wformat-security from being
      re-enabled, which are also part of -Wformat in clang-16.

         It turns out that even after more than a year or development and
         testing, there's not full agreement on whether just using plain
         ordered notifications is Good Enough to avoid the complexity of using
         the notifications slots. Because of that, we decided that it's best
         left to a future final decision.
      
         We can always bring back this feature, but we can't really change it
         or remove it once we've released 6.0 with it enabled. The reverts
         leave the usual CQE notifications as the primary interface for
         knowing when data was sent, and when it was acked. (Pavel)
