+Subject: [PATCH] killall: match on 16 character commlen too
+
+The comm length increase meant killall could accomodate the
+larger comm name given out by newer kernels but it meant that
+if a user relied on the previous 16 character truncation then
+processes that used to match would fail.
+
+killall now checks to see if the the comm is the old COMM_LEN
+length and the given name is longer than old COMM_LEN and does
+a truncated match as well.
