# Pre12 Batch 04: Private compression header
|
|
|
|
## Change
|
|
|
|
- Added `src/compress.h` for the decompressor request, descriptor, and backend
|
|
private declarations previously located in `src/internal.h`.
|
|
- Added the header only to `decompressor.c` and the LZ4, LZMA, Deflate, and
|
|
ZSTD backend translation units.
|
|
- Kept the runtime compression enum, `z_erofs_parse_cfgs`, and the public
|
|
`z_erofs_decompress` declaration in `src/internal.h`.
|
|
- Preserved every migrated declaration signature and storage duration. No
|
|
function body, callback, conditional compilation block, errno path, or
|
|
buffer ownership changed.
|
|
|
|
## Static validation
|
|
|
|
- The `compress.h` consumer set is exactly the five planned decompressor
|
|
translation units; `super.c`, `zdata.c`, and all other public callers still
|
|
include only `internal.h`.
|
|
- The include graph is acyclic: `compress.h` includes `internal.h`, while
|
|
`internal.h` does not include `compress.h`.
|
|
- Exact searches found one definition of each migrated structure and one
|
|
declaration of each migrated backend function. The old declarations are
|
|
absent from `internal.h`.
|
|
- The new header contains no Linux page, folio, bio, workqueue, XArray,
|
|
shrinker, compatibility, or related runtime declarations.
|
|
- Source diff inspection and declaration normalization confirmed that this is
|
|
a declaration-only move plus the five include additions.
|
|
- `git diff --check` and `git diff --cached --check` completed without errors.
|
|
|
|
## Tests not run
|
|
|
|
Per the execution constraints, no build, QEMU run, smoke test, feature test,
|
|
or other dynamic test was run. The planned `WITH_ZSTDIO=0` and
|
|
`WITH_ZSTDIO=1` KLD builds remain required during final validation.
