tmp_dentry dereference ?

[Joilnen Leite]

here i think that d_alloc can return NULL, so
tmp_dentry not use without checked.


fs/cifs/file.c:1251

} else {
      tmp_dentry = d_alloc(file->f_dentry, qstring);
      *ptmp_inode = new_inode(file->f_dentry->d_sb);
      tmp_dentry->d_op = &cifs_dentry_ops;
      cFYI(0, (" instantiate dentry 0x%p with inode
0x%p ",
                tmp_dentry, *ptmp_inode));
      d_instantiate(tmp_dentry, *ptmp_inode);
      d_rehash(tmp_dentry);
}
