    NFS: Fix fdatasync/fsync() when confronted with a server reboot · 05990d1b
    Trond Myklebust authored
    If the server reboots before it can commit the unstable writes to disk,
    then nfs_commit_release_pages() will detect this when it compares the
    verifier returned by COMMIT to the one returned by WRITE. When this
    happens, the client needs to resend those writes in order to guarantee
    that they make it to stable storage.
    
    This patch adds a signalling mechanism to notify fsync() that it
    needs to retry all writes before it can exit.
