Patchset contains cleanup and bug fixes. Patch 1 is the removal
of some redundant code/functions. Patch 2 and 3 are fixes for 
corner cases identified by syzkaller. I've not been able to
reproduce the actual use-after-free race flagged in the syzkaller
reports, thus these fixes are based on code inspection plus 
manual testing to make sure the modified code paths are executed 
without problems in the commonly encountered timing cases.

Series applied, thanks.
