7 years agoscsi: storvsc: remove unnecessary channel inbound lock

scsi: storvsc: remove unnecessary channel inbound lock

In storvsc driver, inbound messages do not go through inbound lock.  The
only effect of this lock was is to provide a barrier for connect and
remove logic.

space. For 32bit srb commands use GFP_DMA32 to limit the memory to 32bit

compiler, clang: properly override 'inline' for clang

Commit abb2ea7dfd82 ("compiler, clang: suppress warning for unused
static inline functions") just caused more warnings due to re-defining
the 'inline' macro.

So undef it before re-defining it, and also add the 'notrace' attribute
like the gcc version that this is overriding does.

Maybe this makes clang happier.

  We've been hitting an early enospc problem on production machines that
  Omar tracked down to an old int->u64 mistake. I waited a bit on this
  pull to make sure it was really the problem from production, but it's
  on ~2100 hosts now and I think we're good.

  Omar also noticed a commit in the queue would make new early ENOSPC
  problems. I pulled that out for now, which is why the top three
  commits are younger than the rest.

  Otherwise these are all fixes, some explaining very old bugs that
  we've been poking at for a while"
