      Pull flexible-array member conversion from Gustavo Silva:
       "The current codebase makes use of the zero-length array language
        extension to the C90 standard, but the preferred mechanism to declare
        variable-length types such as these ones is a flexible array
        member[1][2], introduced in C99:
      
          struct foo {
              int stuff;
              struct boo array[];
          };
      
        By making use of the mechanism above, we will get a compiler warning
        in case the flexible array does not occur last in the structure, which
        will help us prevent some kind of undefined behavior bugs from being
        inadvertently introduced[3] to the codebase from now on.
      
        Also, notice that, dynamic memory allocations won't be affected by
        this change:
      
         "Flexible array members have incomplete type, and so the sizeof
          operator may not be applied. As a quirk of the original
          implementation of zero-length arrays, sizeof evaluates to zero."[1]
      
        sizeof(flexible-array-member) triggers a warning because flexible
        array members have incomplete type[1]. There are some instances of
        code in which the sizeof operator is being incorrectly/erroneously
        applied to zero-length arrays and the result is zero. Such instances
        may be hiding some bugs. So, this work (flexible-array member
        convertions) will also help to get completely rid of those sorts of
        issues.
      
        Notice that all of these patches have been baking in linux-next for
        quite a while now and, 238 more of these patches have already been
        merged into 5.7-rc1.
      
        There are a couple hundred more of these issues waiting to be
        addressed in the whole codebase"

      sched: topology.h: Replace zero-length array with flexible-array member · fe946db6
      Gustavo A. R. Silva authored
      The current codebase makes use of the zero-length array language
      extension to the C90 standard, but the preferred mechanism to declare
      variable-length types such as these ones is a flexible array member[1][2],
      introduced in C99:
      
      struct foo {
              int stuff;
              struct boo array[];
      };
      
      By making use of the mechanism above, we will get a compiler warning
      in case the flexible array does not occur last in the structure, which
      will help us prevent some kind of undefined behavior bugs from being
      inadvertently introduced[3] to the codebase from now on.
      
      Also, notice that, dynamic memory allocations won't be affected by
      this change:
      
      "Flexible array members have incomplete type, and so the sizeof operator
      may not be applied. As a quirk of the original implementation of
      zero-length arrays, sizeof evaluates to zero."[1]

              struct boo array[];

      By making use of the mechanism above, we will get a compiler warning
      in case the flexible array does not occur last in the structure, which
      will help us prevent some kind of undefined behavior bugs from being
      inadvertently introduced[3] to the codebase from now on.
      
      Also, notice that, dynamic memory allocations won't be affected by
      this change:
      
      "Flexible array members have incomplete type, and so the sizeof operator
      may not be applied. As a quirk of the original implementation of
      zero-length arrays, sizeof evaluates to zero."[1]
      
      This issue was found with the help of Coccinelle.

      dirent.h: Replace zero-length array with flexible-array member · a2008395

      extension to the C90 standard, but the preferred mechanism to declare
      variable-length types such as these ones is a flexible array member[1][2],
