Why

linux/docs/adding-drivers.md named three paths that do not exist (src/ddl.rs twice, tests/integration/main.rs), and the fast job's docs step never read it, so nothing caught them. Member manifests also listed tokio and tokio-util features the workspace entry already turns on, which reads as if each crate needed more than it gets.

Change

• The three references now name real files, and the fast job's check-doc-symbols.sh step reads adding-drivers.md too.
• Members list only features their workspace entry does not name; the driver template in the doc follows.

Verified

scripts/check-doc-symbols.sh over the fast job's list is clean. cargo tree -e features for every package, alone and with dev edges, plus the workspace and cargo metadata resolve features: 33,412 lines, identical before and after.

Not in this PR

• error-handling.md, the five driver pages and linux/README.md still have 14 stale references between them and stay outside the check.
