Update our vendored copy of `zerocopy` (and `zerocopy-derive`) to v0.8.54.
It is a very small delta from v0.8.52, and most importantly it resolves
the unexpected lack of inlining [1] which triggered a modpost error
under `CONFIG_CC_OPTIMIZE_FOR_SIZE=y` reported by Alexandre using Gary's
suggestion [2]:
ERROR: modpost: "_RNvMNtCs5wX7wwEUCR9_8zerocopy6layoutNtB2_8SizeInfo24try_to_nonzero_elem_size" [drivers/gpu/nova-core.ko] undefined!
ERROR: modpost: "_RNvNtCs5wX7wwEUCR9_8zerocopy4util18padding_needed_for" [drivers/gpu/nova-core.ko] undefined!
It also resolves `most_traits` being unexpectedly documented [3] that I
reported and adds a missing SPDX license identifier [4] that I requested
to match the kernel version.
The following script may be used to check for the remaining differences:
for path in $(cd rust/zerocopy-derive/ && find . -type f ! -name README.md); do
curl --silent --show-error --location \
https://github.com/google/zerocopy/raw/v0.8.54/zerocopy/zerocopy-derive/src/$path |
git diff --no-index - rust/zerocopy-derive/$path &&
echo $path: OK
done
for path in $(cd rust/zerocopy/ && find . -type f ! -name README.md); do
curl --silent --show-error --location \
https://github.com/google/zerocopy/raw/v0.8.54/zerocopy/$path |
git diff --no-index - rust/zerocopy/$path &&
echo $path: OK
done
