4cf3e6dff7 libceph: export osd_req_op_data() macro
We already have one exported wrapper around it for extent.osd_data and
rbd_object_map_update_finish() needs another one for cls.request_data.

68ada915ee libceph: change ceph_osdc_call() to take page vector for response
This will be used for loading object map.  rbd_obj_read_sync() isn't
suitable because object map must be accessed through class methods.

49ada6e8dc ceph: more precise CEPH_CLIENT_CAPS_PENDING_CAPSNAP
Client uses this flag to tell mds if there is more cap snap need to
flush. It's mainly for the case that client needs to re-send cap/snap
flushes after mds failover, but CEPH_CAP_ANY_FILE_WR on corresponding
inodes are all released before mds failover.

441d367644 iversion: add a routine to update a raw value with a larger one
Under ceph, clients can be independently updating iversion themselves,
while working under comprehensive sets of caps on an inode. In that
situation we always want to prefer the largest value of a change
attribute. Add a new function that will update a raw value with a larger
one, but otherwise leave it alone.

28ef2db886 timer: Document TIMER_PINNED
The flag hints the user that the pinned timers will always be run on a
static CPU (because that should be what "pinned" means...) but that's
not the truth, at least with the current implementation.

For example, currently if a pinned timer is set up but later mod_timer()
upon the pinned timer is invoked, mod_timer() will still try to queue the
timer on the current processor and migrate the timer if necessary.

Document it a bit with the definition of TIMER_PINNED so that all future
users will use it correctly.

1dd7382b1b net/mlx5: Introduce VHCA tunnel device capability
When using the device emulation feature (introduced in Bluefield-1 SOC),
a privileged function (the device emulation manager) will be able to
create a channel to execute commands on behalf of the emulated function.

This channel will be a general object of type VHCA_TUNNEL that will have
a unique ID for each emulated function. This ID will be passed in each
cmd that will be issued by the emulation SW in a well known offset in
the command header.

This channel is needed since the emulated function doesn't have a normal
command interface to the HCA HW, but some basic configuration for that
function is needed (e.g. initialize and enable the HCA). For that matter,
a specific command-set was defined and only those commands will be issued
by the HCA.

5a0c257f8e NFS: send state management on a single connection.
With NFSv4.1, different network connections need to be explicitly
bound to a session.  During session startup, this is not possible
so only a single connection must be used for session startup.

So add a task flag to disable the default round-robin choice of
connections (when nconnect > 1) and force the use of a single
connection.
Then use that flag on all requests for session management - for
consistence, include NFSv4.0 management (SETCLIENTID) and session
destruction

The reason we don't do an immediate cache invalidation is that we

e2869fb206 net/mlx5: Kconfig, Better organize compilation flags
Always contain all acceleration functions declarations in
'accel' files, independent to the flags setting.
For this, introduce new flags CONFIG_FPGA_{IPSEC/TLS} and use stubs
where needed.

This obsoletes the need for stubs in 'fpga' files. Remove them.

Also use the new flags in Makefile, to decide whether to compile
TLS-specific or IPSEC-specific objects, or not.

This patch introduces 'daxdev_mapping_supported' helper

eef778c99c devres: allow const resource arguments
devm_ioremap_resource() does not currently take 'const' arguments, which
results in a warning from the first driver trying to do it anyway:

  drivers/gpio/gpio-amd-fch.c:171:49: error: passing argument 2 of 'devm_ioremap_resource' discards 'const' qualifier from pointer target type [-Werror=discarded-qualifiers]
    priv->base = devm_ioremap_resource(&pdev->dev, &amd_fch_gpio_iores);
                                                   ^~~~~~~~~~~~~~~~~~~

Change the prototype to allow it, as there is no real reason not to.

later from do_basic_setup() unconditionally), along with the

fd3e007f6c don't bother with registering rootfs
init_mount_tree() can get to rootfs_fs_type directly and that simplifies
a lot of things.  We don't need to register it, we don't need to look
it up *and* we don't need to bother with preventing subsequent userland
mounts.  That's the way we should've done that from the very beginning.

There is a user-visible change, namely the disappearance of "rootfs"
from /proc/filesystems.  Note that it's been unmountable all along
and it didn't show up in /proc/mounts; however, it *is* a user-visible
change and theoretically some script might've been using its presence
in /proc/filesystems to tell 2.4.11+ from earlier kernels.

*IF* any complaints about behaviour change do show up, we could fake
it in /proc/filesystems.  I very much doubt we'll have to, though.
