[PATCH] bug in xfrm_lookup [bugzilla 2017]

[Krishna Kumar <krkumar@xxxxxxxxxx>]

Hi Dave,

One of my earlier patches had a bug in xfrm_lookup() causin schedule()
to get called though MSG_DONTWAIT was specified. I am going to send
the following patch to the bugzilla user who created this bug report
and ask them to test it. I thought I will let you know of this problem
and I will send you a confirmation once I get a response that the problem
is solved.

Thanks,

- KK
