[LTP] [PATCH v2] syscalls/copy_file_range02: use .needs_tmpdir and MAX_LEN

[Petr Vorel]

Hi all,

> Since commit bc514b22, we have removed EXDEV test. all_filesystem
> ,mount_device and mntpoint make no sense. Remove it and use tmpdir.

> As man-page said, when we plan to write at a position past the maximum
> allowed offset, it will return EFBIG. We should USE tst_max_lfs_filesize 
> as dst instead of (tst_max_lfs_fileszie - MIN_OFF). Also, it doesn't affect 
> EOVERFLOW.

Thanks for the fix. I tempted to split these 2 changes into 2 commits,
but in the end kept it in single commit.

Merged (with adjusted commit message and
Reported-by for Murphy Zhou and Signed-off-by for Li as he did a review for
previous version).

Kind regards,
Petr
