What is the expected output? What do you see instead?
According to my understanding, second buffer pool is used to promote read 
performance. so i think i should find read io in ssd.

What version of the product are you using? On what operating system?
mysql-5.5.1-m2-linux-x86_64

Please provide any additional information below.

In buf_flush_buffered_writes and buf_flush_write_block_low methods, when the 
page is written back to disk, why are the behavior of sbp is different? In 
"buf_flush_write_block_low", when found a page in sbp ,just update the stat 
info, bu in "buf_flush_buffered_writes", the page were been delete from sbp

thank you!!

如题，烦请核实验证。

偏移量应该是0x002c吧，是不是笔误? 
如果是0x002c，那下条记录为什么是0x002b呢？这里有点疑问。

David,

I did find any you contact information.

I am interested in your second level cache buffer pool feature.

Can you please contact me ?

在windows7/mysql5.5环境，尝试后发现：
innodb_file_per_table=1 而不是innodb_file_per_table=ON

show variables like 'innodb_file_per_table';的结果是innodb_file_per_table=ON
