Subject[PATCH 2/5] fs: update kernel-doc for vfs_rename()
Date
Commit 9fe61450972d ("namei: introduce struct renamedata") introduces a
new struct for vfs_rename() and makes the vfs_rename() kernel-doc argument
description out of sync.

Move the description of arguments for vfs_rename() to a new kernel-doc for
the struct renamedata to make these descriptions checkable against the
actual implementation.
