Subject: [PATCH v2 0/2] Introduce flexible array struct helpers
Date: Mon, 24 Oct 2022 10:20:56 -0700	[thread overview]
Message-ID: <20221024171848.never.522-kees@kernel.org> (raw)

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
