+Subject: fixes for using make 3.82
+
+From: Jan Beulich <JBeulich@novell.com>
+
+commit 3c955b407a084810f57260d61548cc92c14bc627 upstream.
+
+It doesn't like pattern and explicit rules to be on the same line,
+and it seems to be more picky when matching file (or really directory)
+names with different numbers of trailing slashes.

+
+ net/compat/wext: send different messages to compat tasks
+
+we had a race condition when setting and then
+restoring frag_list. Eric attempted to fix it,
+but the fix created even worse problems.
+
+However, the original motivation I had when I
+added the code that turned out to be racy is
+no longer clear to me, since we only copy up
+to skb->len to userspace, which doesn't include
+the frag_list length. As a result, not doing
+any frag_list clearing and restoring avoids
+the race condition, while not introducing any
+other problems.
+
+Additionally, while preparing this patch I found
+that since none of the remaining netlink code is
+really aware of the frag_list, we need to use the
+original skb's information for packet information
+and credentials. This fixes, for example, the
+group information received by compat tasks.
