           Summary: Make debugging hung frames easier
           Product: GlusterFS
           Version: mainline
            Status: NEW

Description of problem:

At the moment new stack doesn't populate frame->root->unique in all cases. This
makes it difficult to debug hung frames by examining successive state dumps.
Fuse and server xlator populate it whenever they can, but other xlators won't
be able to assign one when they need to create a new frame/stack. What we need
is for unique to be correct. If a stack with same unique is present in
successive statedumps, that means the same operation is still in progress. This
makes finding hung frames part of debugging hung frames easier.
