Description:
According to 

http://dev.mysql.com/doc/refman/5.6/en/innodb-parameters.html#sysvar_innodb_flush_neighbor...

innodb_flush_neighbors is boolean, but in reality it can take three values:

static MYSQL_SYSVAR_ULONG(flush_neighbors, srv_flush_neighbors,
  PLUGIN_VAR_OPCMDARG,
  "Set to 0 (don't flush neighbors from buffer pool),"
  " 1 (flush contiguous neighbors from buffer pool)"
  " or 2 (flush neighbors from buffer pool),"
  " when flushing a block",
  NULL, NULL, 1, 0, 2, 0);

How to repeat:
Grep for MYSQL_SYSVAR in ha_innodb.cc

Note that in bug#69046, there is a request to explain what the impact of these settings are and in which situations they apply.
