# Pre11 Batch B: Vnode Operation Scaffolding
|
|
|
|
## Scope
|
|
|
|
This batch is a behavior-preserving cleanup limited to vnode operation
|
|
scaffolding:
|
|
|
|
- removed the unused `EROFS_MOUNT_XATTR_USER` option bit;
|
|
- removed the zero-consumer `erofs_node.vnode` field and its only assignment;
|
|
- grouped VOP forward declarations and `erofs_vnodeops` initializers by
|
|
responsibility.
|
|
|
|
No function definitions, VOP registrations, lock or reclaim behavior,
|
|
`vnode_create_vobject()` error handling, or FIFO operations were changed.
|
|
|
|
## Consumer Audit
|
|
|
|
Before the edit, `EROFS_MOUNT_XATTR_USER` appeared only at its definition.
|
|
The `erofs_node.vnode` member appeared only in the structure definition and in
|
|
the single assignment performed by `erofs_vget()`; it had no read, address, ABI,
|
|
initializer, or offset consumer.
|
|
|
|
After the edit, both removed symbols have zero source-tree matches.
|
|
|
|
## VOP Vector Equivalence
|
|
|
|
Before reordering:
|
|
|
|
- `erofs_vnodeops`: 24 raw entries, 24 unique normalized `field=value` entries;
|
|
- `erofs_fifoops`: 14 raw entries, 14 unique normalized `field=value` entries.
|
|
|
|
After reordering:
|
|
|
|
- `erofs_vnodeops`: 24 raw entries, 24 unique entries, with the sorted
|
|
normalized set identical to the before snapshot;
|
|
- `erofs_fifoops`: 14 raw entries, 14 unique entries, with both the sorted set
|
|
and original entry sequence identical to the before snapshot.
|
|
|
|
## Validation
|
|
|
|
The batch uses static checks only:
|
|
|
|
- normalized before/after VOP vector set comparison;
|
|
- raw entry count versus unique entry count;
|
|
- removed-symbol zero-consumer search;
|
|
- changed-path whitelist;
|
|
- `git diff --check` and conflict-marker scan.
|
|
|
|
No build, QEMU smoke test, or feature test was run for this mechanical batch.
