Any rescue other than recompiling the kernel when the kernel function is inlined?

This is not because of "inline" - DWARF contains debug information for
all occurrences of the inline calls and theoretically STAP could place
breakpoints in all such places. The problem is that due to a
compilation flag there is no debug information for the specific inline
function in the specific kernel build (if my understanding is
correct).

My best advice is to try to look for alternative places in the code to
place a breakpoint.
