Hi Linus, Please pull this tiny overflow helper addition for v5.8-rc2. During the treewide clean-ups of zero-length "flexible arrays", the struct_size() helper was heavily used, but it was noticed that many times it would have been nice to have an additional helper to get the size of just the flexible array itself. This need appears to be even more common when cleaning up the 1-byte array "flexible arrays", so Gustavo implemented it. I'd love to get this landed before -rc2 so it can be used during the v5.9 dev cycle to ease the 1-byte array cleanups.
Thanks! -Kees The following changes since commit b3a9e3b9622ae10064826dccb4f7a52bd88c7407: Linux 5.8-rc1 (2020-06-14 12:45:04 -0700) are available in the Git repository at: https://git.kernel.org/pub/scm/linux/kernel/git/kees/linux.git tags/overflow-v5.8-rc2 for you to fetch changes up to b19d57d0f3cc6f1022edf94daf1d70506a09e3c2: overflow.h: Add flex_array_size() helper (2020-06-16 20:45:08 -0700) ---------------------------------------------------------------- Add flex-array size helper ---------------------------------------------------------------- Gustavo A.
