Calling functions while holding a spinlock

[Barret Rhoden <brho@xxxxxxxxxx>]

Hi -

Would it be possible to add logic to the verifier to handle calling 
functions within my program (subprograms?) while holding a bpf_spin_lock?

Some of my functions are large enough that the compiler won't inline 
them, so I'll get a BPF_CALL to PC + offset (relative call within my 
program).  Whenever this pops up, I force the compiler to inline the 
function, but that's brittle.  I'd rather just have the ability to call 
a function.

Thanks,

Barret
