blktrace: Use number of online CPUs Currently, blktrace uses _SC_NPROCESSORS_CONF to find out the number of CPUs. This is a problem, because if you reduce the number of online CPUs by passing kernel parameter maxcpus, then blktrace fails to start with the error: FAILED to start thread on CPU 4: 22/Invalid argument FAILED to start thread on CPU 5: 22/Invalid argument ... The attached patch fixes it to use _SC_NPROCESSORS_ONLN. Signed-off-by: Jens Axboe <axboe@fb.com>
