Subject: f2fs: remove duplicate code in f2fs_file_write_iter
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=0b86f78920919cf36239f4e187ebad7f5d78b5f8;p=linux.git

f2fs: remove duplicate code in f2fs_file_write_iter

We will do the same check in generic_write_checks.
if (iocb->ki_flags & IOCB_NOWAIT) && !(iocb->ki_flags & IOCB_DIRECT)
        return -EINVAL;
just remove the same check in f2fs_file_write_iter.
