Hi,

Here's a trimmed-down version of my original proposal, which just includes
flex_cpy(), as this is needed by XFS.

-Kees

v2: only include flex_cpy(), leaving remaining helpers for the future
v1: https://lore.kernel.org/all/20220504014440.3697851-1-keescook@chromium.org/

Kees Cook (2):
  Introduce flexible array struct helpers
  xfs: Use flex_cpy() to check extent copying
