For many reasons, forcibly unmounting a soft NFS mount could hang forever. Here are the fixes: - Introduce decents timeouts in operation that awaited NFS server reply. - On timeout, fails operations on soft mounts with EIO. - Introduce NFSMNT_DISMNTFORCE to let the filesystem know that a force unmount is ongoing. This causes timeouts to be reduced and prevents the NFS client to attempt reconnecting to the NFS server. Also fix a race condition where some asynchronous I/O could reference destroyed mount structures. We fix this by awaiting asynchronous I/O to drain before proceeding. Reviewed by Chuck Silvers. |
