NAME
       dget - get a reference to a dentry

SYNOPSIS
       struct dentry * dget(struct dentry * dentry);

ARGUMENTS
       dentry
	   dentry to get a reference to

DESCRIPTION
       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.	dget 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 dget_locked instead of
       dget.
