[Tarantool-patches] [PATCH luajit 0/5] Self-sufficient LuaJIT testing environment

[Igor Munkin]

I've checked the patchset into all long-term branches in
tarantool/luajit and bumped a new version in 1.10, 2.6, 2.7 and master.

NB: there is no separate commit with submodule bump, since there are
many change in LuaJIT build system in Tarantool repo too. For more info
see this series[1].
