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.
