[ofa-general] Re: [PATCH] Corrects a race in ipoib_cm_post_receive_nonsrq()

Roland,

      It's a team work debugging and testing effort. The problem is for
each connection, ipoib_cm_post_receive_nonsrq() gets called, it uses a
shared structure, which overwrite by each other. So one QP's post_recv will
go to another QP context.

Thanks
Shirley

Please be explicit about what the race is, so that I don't have to
repeat your debugging work.

How does Pradeep figure into this?  Is he the original author of this
patch?  By default when I import this into git, the From: line of your
email will be used as the author, so you (David) will be the author.

If you are sending a patch that someone else wrote, please include a
line in the body of your email like

From: Pradeep Satyanarayana <pradeep at us.ibm.com>

showing the original author.
