Subject: Don't set FIO_FILE_extend when create_on_open= option is set
X-Git-Tag: fio-2.19~46
X-Git-Url: https://git.kernel.dk/?p=fio.git;a=commitdiff_plain;h=435584068dad5d4d2464017c3c258673b0ddd74a;hp=12bb8569a2cff7c3905e5a3a132069f47a861d12

Don't set FIO_FILE_extend when create_on_open= option is set

FIO_FILE_extend gets set and later cleared only when create_on_open=
is disabled (which is default). If create_on_open=1 is set this flag
could be set for the entire runtime, but this flag is basically
designed to be enabled only during setup time.

(If there's no "Layint out IO file..." message, both FIO_FILE_extend
and need_extend probably aren't even needed, as files can be extended
at the moment when these flag/variable are set)
