# Pre-12 Batch 08: xattr helper order

Date: 2026-08-13

## Scope

- Moved the complete `static erofs_listxattr_foreach` function block to
  immediately precede `erofs_getxattr_foreach` in `src/xattr.c`.
- Made no changes to either function body, signature, visibility, callers, or
  conditional-compilation context.

## Static proof

- The exact function block from `static int` through its closing brace had
  SHA-256 `0541c211f78a19f39caeebdafe73bdd0a7064e996686a7b45c9c651160ed98ae`
  before and after the move.
- The target remains one `static` definition with two call sites, in the
  inline and shared xattr iterators.
- `erofs_getxattr_foreach` remains one definition with the same two call
  sites; its complete block is unchanged.
- Both helpers remain in the same unconditional compilation region after
  `struct erofs_xattr_iter` and before the iterator functions, so no forward
  declaration or conditional boundary was introduced.
- The source diff is a pure block move; adjacent xattr and ACL logic is
  unchanged.
- `git diff --check` and `git diff --cached --check` were required for this
  batch.

## Deferred validation

No build, QEMU, smoke, feature, or other dynamic validation was run for this
batch. Final KLD and Plain/LZ4/LZMA validation remains deferred.
