Hello,
just wanted to report that I see the same messages with 3.7.0-rc4 and a
Raid0 on two SSD's (Crucial M4):

G'day Shaohua,

cc Martin to check if he has idea.
Hmm, I thought such problem is already fixed by Martin's discard merge patches
and my last test in SATA SSD doesn't show this problem. Maybe there is still
a corner case we didn't handle discard request merge well. Time run out today,
I'll check tomorrow.
Thanks,
Shaohua
