Comment 6 Jian Li 2012-02-28 01:46:47 UTC 
This patch is tested with linux/samba. And the bug can't be reproduced with solaris 11, which maybe fix its own problem.  But in my case, I have tested kinds of wsize, and general IO is tested with difference wsize by fsx program.

In my case wsize takes value of :
131008,65536, 60000, 131008, 18000, 16777151, 1048576.
