This's a regression test for linux 6b4b8e6b4ad8 ("ext4: fix bug for
rename with RENAME_WHITEOUT"). Rename a file with RENAME_WHITEOUT
flag might cause corruption when there's not enough space to
complete this renaming operation.

Hi,
Thanks for the reviewing from Eryu. V2 did below changes:
1) Import ./common/renameat2 and _require_renameat2 whiteout
2) Replace CHUNKS with NR_FILE
3) Reduce the number of test files from 64*64 to 4*64
4) Add to quick group
More details about the reviewing history, refer to:
https://patchwork.kernel.org/project/fstests/patch/20210218071324.50413-1-zlang@redhat.com/
Thanks,
Zorro

Seems reasonable to me; does it pass on xfs?
If so,

Yes, it's passed on xfs and latest ext4(fixed this bug).

Hi Eryu,
Sorry I made a typo mistake on the patch subject, The 'sapce' should be 'space'.
If you don't mind, please help to modify it when you merge this patch. Or feel
free to tell me, if you need I re-send this patch again.
Thanks,
Zorro
