Bug Description

UNIV_INTERN ulint srv_cleaner_flush_chunk_size = 200;

static MYSQL_SYSVAR_ULONG(cleaner_flush_chunk_size,
  srv_cleaner_flush_chunk_size,
  PLUGIN_VAR_RQCMDARG,
  "Divide page cleaner flush list flush batches into chunks of this size",
  NULL, NULL, 100, 1, ~0UL, 0);

This was discovered before the GA, and attempted to fix with bug 1235114 branch, and with xtradb-empty-free-list-backoff. These two "fixes" crossed each other, reversing the mismatch.

The correct default is 100.
