cluster/afr: Make local->child_up immutable

2011-09-21T11:25:15+00:00

Afr transaction performs lock, pre-op, op, post-op and unlock steps in that
order. The child_up[] is overloaded with the information of where all
the first two steps succeeded. This works perfectly fine for
Transaction, but the locking/unlocking part of the code is re-used by
data self-heal. In that each loop_frame does lock, rchecksum,
read-from-source and write-to-sinks, unlock steps.

Rchecksum fop assumes that the fop needs to happen on one source + all
sinks and sets the call_count to that number. But if the lock step fails
on any of the sinks it will mark the child_up of that child to 0, which
will result in call_count mismatch and the frame will hang thinking that
some more cbks need to come. When this happens loop_frame will never go
to unlock step leading to hangs on that file.

Eliminate many "var set but not used" warnings with newer gcc.

2011-09-08T06:48:01+00:00

This fixes ~200 such warnings, but leaves three categories untouched.

(1) Rpcgen code.

(2) Macros which set variables in the outer (calling function) scope.

(3) Variables which are set via function calls which may have side effects.
