Subject: [PATCH] Must use ->real_file_size
X-Git-Tag: fio-1.10~9
X-Git-Url: https://git.kernel.dk/?p=fio.git;a=commitdiff_plain;h=ee88470c001012d08ae37bfc31741a935be2e7a1;ds=inline

[PATCH] Must use ->real_file_size

->file_size is the size of the file from offset, while ->real_file_size
is the total size of the file. So when comparing EOF, we should look
at ->real_file_size against the offset.
