dget(9)
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.
