Line 1298: def cpu_mask_to_bits(cpus):
Line 1299: mask = 0
> move below at the beginning of the for loop (this isn't C :) )
to be a bit less C-ish, 'index' sounds nicer ;) (applies also for above)
Line 1300: if not cpus:
Line 1301: return CPU_ANY
Line 1302:
Line 1303: for idx in _expand_cpu_list(cpus):

Line 1302:
Line 1303: for idx in _expand_cpu_list(cpus):
Line 1304: mask = _enable_cpu(mask, idx)
This feels hard to read to me - what about returning only the shift and doing mask |= _enable_cpu_{shift, mask, ??}(mask, index) ?

add '-' as a test case (for peace of mind ;) )
