When a file is deleted on the NFS server by another client, any NFSv4 state related to that file is left stranded. This happens because the NFSv4 operations that free the state use a CFH, which is set by a PutFH operation. However, the PutFH fails with ESTALE because the file has been deleted. This patch adds a function called nfsrv_freestrandedstate() that frees all the NFSv4 state related to a file and calls this function when PutFH will be replying ESTALE. While here, a helper function was defined to handle free'ng of the nfslockfile structure and replaces the two places where nearly identical code does this.

FreeBSD Source:
This is the top level of the FreeBSD source directory.
FreeBSD is an operating system used to power modern servers, desktops, and embedded platforms. A large community has continually developed it for more than thirty years. Its advanced networking, security, and storage features have made FreeBSD the platform of choice for many of the busiest web sites and most pervasive embedded networking and storage devices.
