Subject: [net/9p] Set the condition just before waking up.
X-Git-Tag: v2.6.39-rc1~381^2~3
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=a01a984035ea799b14aa5e874dcaeb122f09c4b4;p=pandora-kernel.git

[net/9p] Set the condition just before waking up.

Given that the sprious wake-ups are common, we need to move the
condition setting right next to the wake_up().  After setting the condition
to req->status = REQ_STATUS_RCVD, sprious wakeups may cause the
virtqueue back on the free list for someone else to use.
This may result in kernel panic while relasing the pinned pages
in p9_release_req_pages().

Also rearranged the while loop in req_done() for better redability.
