[PATCH v3] VFS: d_duplicate: repair comments to avoid kernel-doc warnings

[Randy Dunlap <rdunlap@infradead.org>]

Use a typical list style for comments to prevent kernel-doc warnings:

Documentation/filesystems/api-summary:20: ../fs/dcache.c:2029: ERROR: Unexpected indentation. [docutils]
Documentation/filesystems/api-summary:20: ../fs/dcache.c:2030: WARNING: Block quote ends without a blank line; unexpected unindent. [docutils]

Also, modify the spelling of "whiteout" to match all other uses in
the kernel source tree and to be consistent on the same line.

Fixes: 33d76519f0cc ("VFS: add d_duplicate()")

v3: use one colon for the list, not "::" for a literal block (Neil).

  * For this they need two dentries which temporarily have the same name,
