Unfortunately I am having an issue with buffer_compress_chunk in the
2.2.12 release. Removing buffer_compress_chunk from the tests below
fixes the issues.
fio --name=test --rw=write --bs=4k --ioengine=libaio --direct=1
--iodepth=32 --size=1g --refill_buffers
--buffer_compress_percentage=50 --buffer_compress_chunk=32k
--filename=testfile
test: (g=0): rw=write, bs=4K-4K/4K-4K/4K-4K, ioengine=libaio, iodepth=32

That's odd, I can't reproduce that. Could this just be a bad build? Fio
sometimes fails to rebuild correctly between version. Does it persist
across a make clean && make?
