+Subject: [PATCH] block: disallow block jobs when there is a BDRV_O_INACTIVE
+ flag
+
+Currently, migration will put a BDRV_O_INACTIVE flag
+on bs's open_flags until another resume being called. In that case,
+any IO from vm or block jobs will cause a qemu crash with an assert
+'assert(!(bs->open_flags & BDRV_O_INACTIVE))' failure in bdrv_co_pwritev
+function. we hereby disallow block jobs by faking a blocker.
