The all target now depends on .git/hooks/pre-commit, which is created by install-hooks. This ensures git hooks are active after the first make invocation without manual setup. Change-Id: Ia11781ed707d69ed70921580c93f0a65ff77d667

Sorry, something went wrong.
Nightly workflow (build-lkl.yml) builds liblkl.a for x86_64 and aarch64 in parallel, checks upstream lkl/linux HEAD to skip redundant rebuilds, and publishes to the lkl-nightly release on sysprog21/kbox with delete-then-create semantics. Build-and-test workflow (build-kbox.yml) splits unit tests from integration tests for parallelism: unit tests run immediately (no LKL dependency) while the build job fetches LKL, compiles, and prepares the rootfs. fetch-lkl.sh now fetches from sysprog21/kbox lkl-nightly release instead of querying lkl/linux releases. Auto-detects host arch. Also adds LKL API surface doc, threading mode analysis, LSAN suppression file for known LKL leaks, and ABI warning on manually-declared struct lkl_disk. The cache key derived from lkl-sha256.txt (currently comments-only) is effectively static, and restore-keys can serve stale artifacts that fetch-lkl.sh never validates. The nightly tarball is small enough that fetching it each run is simpler and always correct. Change-Id: Id36c47d6a304ea0c2bed3355e1d293a6c32542d4
