Rick Macklem 64a0e848ab When an NFS unmount occurs, once vflush() writes the last dirty ... buffer for the last vnode on the mount back to the server, it returns. At that point, the code continues with the unmount, including freeing up the nfs specific part of the mount structure. It is possible that an nfsiod thread will try to check for an empty I/O queue in the nfs specific part of the mount structure after it has been free'd by the unmount. This patch avoids this problem by setting the iodmount entries for the mount back to NULL while holding the mutex in the unmount and checking the appropriate entry is non-NULL after acquiring the mutex in the nfsiod thread.
