I am going to test it now, just one thing: when introducing new lock flags
etc. please also fix debugging code, so in log new flags appear decoded.

I mean
@@ -145,7 +145,8 @@ static const char *decode_flags(unsigned char flags)
 {
 	static char buf[128];
 
-	sprintf(buf, "0x%x (%s%s)", flags,
+	sprintf(buf, "0x%x (%s%s%s)", flags,
+		flags & LCK_PARTIAL_MODE	  ? "PARTIAL_MODE " : "",
 		flags & LCK_MIRROR_NOSYNC_MODE	  ? "MIRROR_NOSYNC " : "",
 		flags & LCK_DMEVENTD_MONITOR_MODE ? "DMEVENTD_MONITOR " : "");


Also do_lock_lv() should clear cmd->partial_activation before releasing lvm_lock,
(all flags are handled that way, so better do not change logic here).
