.SH NAME
dget \- get a reference to a dentry
.SH SYNOPSIS
.sp
\fB
.sp
struct dentry * dget  (struct dentry * \fIdentry\fB);
\fR
.SH "ARGUMENTS"
.TP
\fB\fIdentry\fB\fR
dentry to get a reference to
.SH "DESCRIPTION"
.PP
Given a dentry or NULL pointer increment the reference count
if appropriate and return the dentry. A dentry will not be 
destroyed when it has references. \fBdget\fR should never be
called for dentries with zero reference counter. For these cases
(preferably none, functions in dcache.c are sufficient for normal
needs and they take necessary precautions) you should hold dcache_lock
and call \fBdget_locked\fR instead of \fBdget\fR.
