When the first time pynfs runs after rpc/nfsd startup, always get the warning,
"Got error: Connection closed"
I found the problem is caused by,
1. A new startup of nfsd, rpc.mountd, etc,
2. A rpc request from client (pynfs test, or normal mounting),
3. An ip_map cache is created but invalid, so upcall to rpc.mountd,
4. rpc.mountd process the ip_map upcall, before write the valid data to nfsd,
do auth_reload(), and check_useipaddr(),
5. For the first time, old_use_ipaddr = -1, it causes rpc.mountd do write_flush that doing cache_clean,
6. The ip_map cache will be treat as expired and clean,
7. When rpc.mountd write the valid data to nfsd, a new ip_map is created
and updated, the cache_check of old ip_map(doing the upcall) will
return -ETIMEDOUT.
8. RPC layer return SVC_CLOSE and close the xprt after commit 4d712ef1db05
"svcauth_gss: Close connection when dropping an incoming message"
NeilBrown suggest in another email,
"If CACHE_VALID is not set, then there is no data in the cache item,
so there is nothing to expire. So it would be nice if cache items that
don't have CACHE_VALID are never treated as expired."
v3, change the order of the two patches
v2, change the checking of CACHE_PENDING to CACHE_VALID

Add a new merge strategy that merges discard bios into a request until the
maximum number of discard ranges (or the maximum discard size) is reached
from the plug merging code. I/O scheduler merging is not wired up yet
but might also be useful, although not for fast devices like NVMe which
are the only user for now.
Note that for now we don't support limiting the size of each discard range,

When a multipath route is hit the kernel doesn't consider nexthops that
are DEAD or LINKDOWN when IN_DEV_IGNORE_ROUTES_WITH_LINKDOWN is set.
Devices that offload multipath routes need to be made aware of nexthop
status changes. Otherwise, the device will keep forwarding packets to
non-functional nexthops.
Add the FIB_EVENT_NH_{ADD,DEL} events to the fib notification chain,
which notify capable devices when they should add or delete a nexthop
from their tables.

Replace C structure-based XDR decoding with pointer arithmetic.
Pointer arithmetic is considered more portable, and is used
throughout the kernel's existing XDR encoders. The gcc optimizer
generates similar assembler code either way.
Byte-swapping before a memory store on x86 typically results in an
instruction pipeline stall. Avoid byte-swapping when encoding a new
header.
svcrdma currently doesn't alter a connection's credit grant value
after the connection has been accepted, so it is effectively a
constant. Cache the byte-swapped value in a separate field.
Christoph suggested pulling the header encoding logic into the only
function that uses it.

The stack must not pass packets to device drivers that are shorter
than the minimum link layer header length.
Previously, packet sockets would drop packets smaller than or equal
to dev->hard_header_len, but this has false positives. Zero length
payload is used over Ethernet. Other link layer protocols support
variable length headers. Support for validation of these protocols
removed the min length check for all protocols.
Introduce an explicit dev->min_header_len parameter and drop all
packets below this value. Initially, set it to non-zero only for
Ethernet and loopback. Other protocols can follow in a patch to
net-next.

This patch addresses a long-standing bug with multi-session
(eg: iscsi-target + iser-target) se_node_acl dynamic free
withini transport_deregister_session().
This bug is caused when a storage endpoint is configured with
demo-mode (generate_node_acls = 1 + cache_dynamic_acls = 1)
initiators, and initiator login creates a new dynamic node acl
and attaches two sessions to it.
After that, demo-mode for the storage instance is disabled via
configfs (generate_node_acls = 0 + cache_dynamic_acls = 0) and
the existing dynamic acl is never converted to an explicit ACL.
The end result is dynamic acl resources are released twice when
the sessions are shutdown in transport_deregister_session().
If the storage instance is not changed to disable demo-mode,
or the dynamic acl is converted to an explict ACL, or there
is only a single session associated with the dynamic ACL,
the bug is not triggered.
To address this big, move the release of dynamic se_node_acl
memory into target_complete_nacl() so it's only freed once
when se_node_acl->acl_kref reaches zero.

Back in the days when the GICv3/v4 architecture was drafted,
the command to an event to an LPI number was called MAPVI.
Later on, and to avoid confusion with the GICv4 command VMAPI,
it was renamed MAPTI. We've carried the old name for a long
time, but it gets in the way of people reading the code in
the light of the public architecture specification.
Just repaint all the references and kill the old definition.

During the development of the GICv3/v4 architecture, it was
envisaged to have a CPU table, though the use for it was
never completely clear (the collection table serves that role
pretty well). It ended being dropped before the specification
was published, though it lived on in the driver.
In order to avoid people scratching their head too much, let's do
the same in the kernel.

set representation scalability in terms of memory. The size field is
still left in place so use this if the userspace provides no explicit

This patch extends the idea of NMI per-cpu buffers to regions
that may cause recursive printk() calls and possible deadlocks.
Namely, printk() can't handle printk calls from schedule code
or printk() calls from lock debugging code (spin_dump() for instance);
because those may be called with `sem->lock' already taken or any
other `critical' locks (p->pi_lock, etc.). An example of deadlock
can be
vprintk_emit()
console_unlock()
up() << raw_spin_lock_irqsave(&sem->lock, flags);
wake_up_process()
try_to_wake_up()
ttwu_queue()
ttwu_activate()
activate_task()
enqueue_task()
enqueue_task_fair()
cfs_rq_of()
task_of()
WARN_ON_ONCE(!entity_is_task(se))
vprintk_emit()
console_trylock()
down_trylock()
raw_spin_lock_irqsave(&sem->lock, flags)
^^^^ deadlock
and some other cases.
Just like in NMI implementation, the solution uses a per-cpu
`printk_func' pointer to 'redirect' printk() calls to a 'safe'
callback, that store messages in a per-cpu buffer and flushes
them back to logbuf buffer later.
Usage example:
printk()
printk_safe_enter_irqsave(flags)
//
// any printk() call from here will endup in vprintk_safe(),
// that stores messages in a special per-CPU buffer.
//
printk_safe_exit_irqrestore(flags)
The 'redirection' mechanism, though, has been reworked, as suggested
by Petr Mladek. Instead of using a per-cpu @print_func callback we now
keep a per-cpu printk-context variable and call either default or nmi
vprintk function depending on its value. printk_nmi_entrer/exit and
printk_safe_enter/exit, thus, just set/celar corresponding bits in
printk-context functions.
The patch only adds printk_safe support, we don't use it yet.

Update the drivers to pass the RSSI level as a cfg80211_cqm_rssi_notify
parameter and pass this value to userspace in a new nl80211 attribute.
This helps both userspace and also helps in the implementation of the
multiple RSSI thresholds CQM mechanism.
Note for marvell/mwifiex I pass 0 for the RSSI value because the new
RSSI value is not available to the driver at the time of the
cfg80211_cqm_rssi_notify call, but the driver queries the new value
immediately after that, so it is actually available just a moment later
if we wanted to defer caling cfg80211_cqm_rssi_notify until that moment.
Without this, the new cfg80211 code (patch 3) will call .get_station
which will send a duplicate HostCmd_CMD_RSSI_INFO command to the hardware.

The vblank is mostly CRTC specific and implemented as part of CRTC
driver. Let's keep the vblank hooks struct drm_driver for legacy
drivers, and add corresponding hooks in struct drm_crtc_funcs. These
hooks take struct drm_crtc pointer as argument, and will be called by
core vblank handling code for DRIVER_MODESET drivers.
The new hooks get plugged into core by adding wrapper functions for
vblank handling code. The .get_vblank_counter hook is effectively
optional, as we provide drm_vblank_no_hw_counter() as the default
fallback in the wrapper function.

Noticed that everyone duplicates the same logic here and we could safe
a few lines per driver. Yay for lots of drivers to make such tiny
refactors worth-while!
v2: Forgot to git add everything :(
v3: Actually remove release_fbi (Sean, Emil, Chris) ...
