.SH "ARGUMENTS"
.PP
\fIstruct dentry * old_dir\fR
.RS 4
a pointer to the parent dentry for the renamed object\&. This should be a directory dentry\&.

\fIstruct dentry * old_dentry\fR
.RS 4
dentry of an object to be renamed\&.
.RE
.PP
\fIstruct dentry * new_dir\fR

.SH "DESCRIPTION"
.PP
This function renames a file/directory in debugfs\&. The target must not exist for rename to succeed\&.

will be returned\&.
.PP
If debugfs is not enabled in the kernel, the value \-\fBENODEV\fR
