Marko Mäkelä d0116e10a5 Revert MDEV-18464 and MDEV-12009 ... This reverts commit 21b2fada7a and commit 81d71ee6b2. The MDEV-18464 change introduces a few data race issues. Contrary to the documentation, the field trx_t::victim is not always being protected by lock_sys_t::mutex and trx_t::mutex. Most importantly, it seems that KILL QUERY could wrongly avoid acquiring both mutexes when invoking lock_trx_handle_wait_low(), in case another thread had already set trx->victim=true. We also revert MDEV-12009, because it should depend on the MDEV-18464 fix being present.		2019-03-28 12:39:50 +02:00
