Strangely enough, NIOS2 defines TRACE_IRQFLAGS_SUPPORT twice
with different values, which is pointless and confusing.
[1] arch/nios2/Kconfig
config TRACE_IRQFLAGS_SUPPORT
def_bool n
[2] arch/nios2/Kconfig.debug
config TRACE_IRQFLAGS_SUPPORT
def_bool y
[1] is included before [2]. In the Kconfig syntax, the first one
is effective. So, TRACE_IRQFLAGS_SUPPORT is always 'n'.
The second define in arch/nios2/Kconfig.debug is dead code.

This is a bug in clang that will be fixed in the future, but in order
to build cleanly with clang-8, it would be helpful to shut up this

The best solution I could come up with is to move the BIT() usage
out of the macro into the instantiation, so we can avoid using
BIT(-1).

NFSv4 clients are automatically expired and all their locks removed if
they don't contact the server for a certain amount of time (the lease
period, 90 seconds by default).
There can still be situations where that's not enough, so allow
userspace to force expiry by writing "expire\n" to the new
nfsd/client/#/ctl file.
(The generic "ctl" name is because I expect we may want to allow other
operations on clients in the future.)
The write will not return until the client is expired and all of its
locks and other state removed.
The fault injection code also provides a way of expiring clients, but it
fails if there are any in-progress RPC's referencing the client. Also,
its method of selecting a client to expire is a little more
primitive--it uses an IP address, which can't always uniquely specify an
NFSv4 client.

Add a nfsd/clients/#/opens file to list some information about all the
opens held by the given client, including open modes, device numbers,

and escaping the rest seems useful while still being machine-readable.

I'm exposing some information about NFS clients in pseudofiles. I
expect to eventually have simple tools to help read those pseudofiles.
But it's also helpful if the raw files are human-readable to the extent
possible. It aids debugging and makes them usable on systems that don't
have the latest nfs-utils.
A minor challenge there is opaque client-generated protocol objects like
state owners and client identifiers. Some clients generate those to
include handy information in plain ascii. But they may also include
arbitrary byte sequences.
I think the simplest approach is to limit to isprint(c) && isascii(c)
and escape everything else.
That means you can just cat the file and get something that looks OK.
Also, I'm trying to keep these files legal YAML, which requires them to
UTF-8, and this is a simple way to guarantee that.
