2016-02-09blktrace: Use number of online CPUsAbutalib Aghayev
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 <>
2013-08-01verify_blkparse: Change max_cpus to deal with systems larger the 512Nathan Zimmer
verify_blkpars has troubles with systems larger then 512. Also there is issue in the scanning code causing the cpu number to be truncated to the first two digits. i.e cpu 542 would be read as 54. Cc: Jens Axboe <> Signed-off-by: Nathan Zimmer <> Signed-off-by: Jens Axboe <>

The C version checks a 92MB file in 2 seconds where the php version takes 23 seconds.
