Subject: Add support for >= 4G block sizes
X-Git-Tag: fio-3.9~62
X-Git-Url: https://git.kernel.dk/?p=fio.git;a=commitdiff_plain;h=5fff95436922873dd9ded8b21af7222689e2ec5d

Add support for >= 4G block sizes

For trims, it's useful to be able to support larger than (or equal
to) 4GB. This extends the block sizes support for that.

Change from Jeff, various little fixups from me.
