[PATCH] builtin/maintenance: accept "none" as a maintenance strategy

From: David Lin <hidden>
Date: 2026-07-29 19:41:33
Subsystem: the rest · Maintainer: Linus Torvalds

Commit d465be2327 (builtin/maintenance: don't silently ignore invalid
strategy, 2025-10-24) changed scheduled maintenance to error on an
unknown maintenance strategy instead of silently defaulting to the
`none` strategy.

However, `parse_maintenance_strategy()` does not recognize `none`, so
Git rejects a valid and documented strategy that can be used to override
an existing strategy and disable maintenance tasks.

Accept `none` as a valid maintenance strategy and add tests to ensure
it's accepted.
