Hi Jeff,
Many thanks for jumping on this one and being the first to produce a
functionally correct 'push-down' series. ;) I started in on this on
this conversion last week, but unfortuately did not make it all the way
through as the seasonal flu cut my efforts short.
In any event, I will start rebasing my lock-less efforts upon your patch
and add the extras currently existing in
lio-4.0.git/host_lock-less-for-37-v10 on top of this patch. This
includes the atomic_t for per host serial counter patch and to enable
those LLDs that have gotten maintainer ACKs, or that we think should be
OK (and has had some testing) to function in lockless mode by default.
As I still have my hands full w/ TCM items atm, this is going to take a
few days to respin a patch nut I will aim to get my own lock-less
development VMs converted to running this code by the end of the week /
as the remaining TODO items for TCM v4.0 are addressed.
Thank you!
