Double parens? If a single pair of parens is no longer sufficient, that is news to me (git top of tree seems to take a single pair of surrounding parens ok, and I didn't see a recent commit that looked like a change to require double parens.) Eg: sleekness fio # grep 2k examples/latency-profile.fio bs=(2k+2k) sleekness fio # ./fio examples/latency-profile.fio device: (g=0): rw=randread, bs=4K-4K/4K-4K/4K-4K, ioengine=libaio, iodepth=128 fio-2.1.14-3-g9e311 Starting 1 process ^Cbs: 1 (f=1) fio: terminating on signal 2 -- steve On Tue, Nov 11, 2014 at 3:14 PM, Jens Axboe <axboe@xxxxxxxxx> wrote: > Hi, > > I've released version 2.1.14 today.
