[PATCH] NFS: remove the redundant check when kfree an object in nfs_netns_client_release

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



kfree has taken the null check in account. hence it is unnecessary to add the
null check before kfree the object. Just remove it.
