I see all sorts of inlining complaints from other modules but > not cxgb. Are you sure you don't have a modified make.conf? Actually, yes, I was using a slightly modified make.conf. After playing around for a while it turned out that the "problem" was a CONFIGARGS?=3D-g line, which changed the gcc invocation to -O instead of the default -O2. Again, after playing around with the gcc options a bit, it turns out that -O2 includes -funit-at-a-time, making gcc parse the whole cxgb_sge.c before the compilation, so that it can see the refill_rspq() function body and it can inline it properly. So... I'm not sure what the proper solution ought to be - either figure out a way to add -funit-at-a-time to CFLAGS (which might not work all that well with non-gcc compilers, I guess), or move the function body up as per my original suggestion.
