X-Git-Tag: fio-3.8~27^2~6
X-Git-Url: https://git.kernel.dk/?p=fio.git;a=commitdiff_plain;h=196ccc44e70333cc87f9d417967bd06288602dac;hp=af84cd66149507424814cf9c0b4950f4cf66e3b7

fio.h: also check trim operations in fio_ro_check

IO engines call fio_ro_check to ensure that the data direction
set in the thread data structure permits writes before proceeding
with a write io_u. This patch makes fio_ro_check ensure that the
data direction also permits trims before proceeding with a trim
io_u.
