trx_purge_truncate_history(): Do not force a write of the undo tablespace that is being truncated. Instead, prevent page writes by acquiring an exclusive latch on all dirty pages of the tablespace. fseg_create(): Relax an assertion that could fail if a dirty undo page is being initialized during undo tablespace truncation (and trx_purge_truncate_history() already acquired an exclusive latch on it). fsp_page_create(): If we are truncating a tablespace, try to reuse a page that we may have already latched exclusively (because it was in buf_pool.flush_list). To some extent, this helps the test innodb.undo_truncate,16k to avoid running out of buffer pool. mtr_t::commit_shrink(): Mark as clean all pages that are outside the new bounds of the tablespace, and only add the newly reinitialized pages to the buf_pool.flush_list. buf_page_create(): Do not unnecessarily invoke change buffer merge on undo tablespaces. buf_page_t::clear_oldest_modification(bool temporary): Move some assertions to the caller buf_page_write_complete(). innodb.undo_truncate: Use a bigger innodb_buffer_pool_size=24M. On my system, it would otherwise hang 1 out of 1547 attempts (on the 40th repeat of innodb.undo_truncate,16k). Other page sizes were not affected.
