Adapted from Debian: https://sources.debian.org/patches/sqlite3/3.32.3-1/20-hurd-locking-style.patch Upstream status: Not upstreamed. This patch is needed to get offloading to work. Sqlite can use simple file locking mode, but that does not work for the Hurd; a second sqlite process fails with a "locking protocol" error.
