Amir Goldstein b10cdcdc20 ovl: untangle copy up call chain ... In an attempt to dedup ~100 LOC, we ended up creating a tangled call chain, whose branches merge and diverge in several points according to the immutable c->tmpfile copy up mode. This call chain was hard to analyse for locking correctness because the locking requirements for the c->tmpfile flow were very different from the locking requirements for the !c->tmpfile flow (i.e. directory vs. regulare file copy up). Split the copy up helpers of the c->tmpfile flow from those of the !c->tmpfile (i.e. workdir) flow and remove the c->tmpfile mode from copy up context.
