Since 2.6.25, the behavior of the NFS client has been a mix of the
two. I believe the current behavior is that SIGKILL can terminate an
NFS operation, but all other signals are deferred until pending NFS
operations complete.
I guess this means that commands cannot be terminated using Ctrl-C, since
that generates a SIGINT? If so, this is a change for the worse.
The mount command continues to accept both options, but neither have
any effect on the client's behavior (both options are no-ops).
Note that this behaviour is true of local filesystems too, since
generic_file_read() has been changed to call lock_page_killable()
instead of the uninterruptible lock_page().
I see. However, it's much more common with unreachable network servers
than unreachable local block devices.
