I prefer moving it when the durable handle structures are moved to
/common later.
Thanks.

Posted by ChenXiaoSong 1 month, 3 weeks ago
Hi Namjae,

I'm confused by what this sentence means: "I prefer moving it when the 
durable handle structures are moved to /common later.".

What does "it" refer to? Does "it" refer to the whole patch, or only to 
"SMB2_DHANDLE_FLAG_PERSISTENT"?
