d_lookup — search for a dentry
struct dentry * d_lookup ( | const struct dentry * parent, |
const struct qstr * name); |
dentry, or NULL
d_lookup searches the children of the parent dentry for the name in
question. If the dentry is found its reference count is incremented and the
dentry is returned. The caller must use dput to free the entry when it has
finished using it. NULL is returned if the dentry does not exist.
