- InnoDB fails to check the table is being dropped or evicted
while acquiring the MDL for the table when table open operation
mode is DICT_TABLE_OP_OPEN_ONLY_IF_CACHED. This is caused by
the commit 337bf8ac4b (MDEV-36122)
Fix:
===
dict_acquire_mdl_shared(): If the table is evicted or dropped when
table operation mode is DICT_TABLE_OP_OPEN_IF_CACHED then return
nullptr
