Sergey Vojtovich c0d5d7c0ef MDEV-15104 - Remove trx_sys_t::serialisation_list ... serialisation_list was supposed to instantly give minimum registered transaction serialisation number. However maintaining and accessing this list requires global mutex protection. Since we already take MVCC snapshot by iterating trx_sys_t::rw_trx_hash, it is cheap to integrate minimum registered transaction lookup into this iteration.		2018-01-31 16:23:56 +04:00
