+Subject: [PATCH] udev_sync: cookie_set=1 on each dm_task_set_cookie call
+
+cookie_set variable found in the struct dm_task should be always
+set to 1 after dm_task_set_cookie_call, even if udev_sync is disabled
+as the cookie itself carries synchronization informations *as well as*
+extra flags to control other aspects of udev support.
+
+For example, one could disable the synchronization itself, but still
+direct the libdm code to disable library fallback via
+DM_UDEV_DISABLE_LIBRARY_FALLBACK flag. These extra flags still need
+to be carried out!
+
+A concrete example:
+  $ dmsetup create test --table "0 1 zero" --noudevsync
+
+This disables synchronization with udev. As the --verifyudev option is
+not used, we don't want to do any corrections. In other words, we
+need DM_UDEV_DISABLE_LIBRARY_FALLBACK flag to be used. However,
+with --noudevsync this was not the case - the flag was ignored!
+
+This patch fixes the case when noudevsync is used but there are still
+some extra flags passed within the cookie flag part. The synchronization
+part of the cookie stays zero (which is ok as dm_udev_wait call on such a
+cookie is simply a NOOP).

+ Version 1.02.77 - 15th October 2012
+ ===================================
++  Fix dm_task_set_cookie to properly process udev flags if udev_sync disabled.
+   Support unmount of thin volumes from pool above thin pool threshold.
+   Update man page to reflect that dm UUIDs are being mangled as well.
+   Apply 'dmsetup mangle' for dm UUIDs besides dm names.
