Fwiw, my experience is that if I can't explain the locking to sparse
that's usually a sign that the code is too complex and needs to be
rewritten.
In general I'm in favour of patches to fix sparse warnings. In this
case it looks like what's needed is __cond_acquires, but the patch
to implement that in sparse[1] doesn't seem to have gotten anywhere
near Luc's tree. (Yet it's present and occasionally used in the
kernel...) CCing the sparse ML to find out why.
