"BIG" in the name refers to the amount of data being transferred,
_not_ the size of structure itself; it's 140 or 144 bytes (for
32bit and 64bit hosts resp.). IOCTL_Command_struct is 136 or
144 bytes large...
No point whatsoever turning that into dynamic allocation, let
alone
hpsa compat ioctl done (hopefully) saner. I really want
to kill compat_alloc_user_space() off - it's always trouble and
for a driver-private ioctls it's absolutely pointless.
Note that this is only compile-tested - I don't have the
hardware to test it on *or* userland to issue

Some atmel socs have extra tcb capabilities that allow using a generic
clock source or enabling a quadrature decoder.

Hello,
This series mainly adds sama5d2 support where we need to avoid using
clock index 0 because that clock is never enabled by the driver.
There is also a rework of the 32khz clock handling so it is not used for

In order to improve consistency and usability in cgroup stat accounting,
we would like to support the root cgroup's io.stat.
Since the root cgroup has processes doing io even if the system has no
explicitly created cgroups, we need to be careful to avoid overhead in

ONIE is a small operating system, pre-installed on bare metal network
switches, that provides an environment for automated provisioning.
This system requires that NVMEM (EEPROM) device holds various system
information (mac address, platform name, etc) in a special TLV layout.
The driver
Current implementation does not allow to register nvmem cells for
existing device and requires that this will be done before device is
registered.
But there might a driver which provides only cells info which needs to
be added for already registered nvmem device.

This series adds cells provider for the ONIE TLV attributes which are
stored on NVMEM device. It adds possibility to read the mac address (and
other info) by other drivers.
Driver needs to register NVMEM cells table for already registered
NVMEM device, this requires additional change to the core

Don't use the running state for fileserver probes to make decisions about
which server to use as the state is cleared at the start of a probe and
also intermediate values might be misleading.
Instead, add a separate 'latest known' rtt in the afs_server struct and a
flag to indicate if the server
Fix afs_statfs() so that the value for f_bavail and f_bfree don't go
"negative" if the number of blocks in use by a volume exceeds the max quota

Whilst it shouldn't happen, it is possible for multiple fileservers to

Adjust the fileserver rotation algorithm so that if we've tried all the
addresses on a server (cumulatively over multiple operations) until we've
run out of untried addresses, immediately reprobe all that server's
interfaces and retry the op at least once before we move onto the next
server.
Reorganise afs_volume objects such that they're in a tree keyed on volume
ID, rooted at on an afs_cell object rather than being in multiple trees,
each of which is rooted on an afs_server object.
afs_server structs become per-cell and acquire a pointer to the cell.

Put in the first phase of cell alias detection. This part handles alias
detection for cells that have root.cell volumes (which is expected to be
likely).
When a cell becomes newly active, it is probed for its root.cell volume,
and if it has one, this volume is compared against other root.cell
Save more bits from the volume location database record obtained for a
server so that we can use this information in cell alias detection.

Implement the second phase of cell alias detection. This part handles
alias detection for cells that don't have root.cell volumes and so we have
to find some other volume or fileserver to query.
We take the first volume from each such cell and attempt to look it up in
the new cell. If found, we
The AFS filesystem driver is handling the CB.ProbeUuid request incorrectly.
The UUID presented in the request is that of the cache manager, not the
fileserver, so afs_deliver_cb_probe_uuid() shouldn't be using that UUID to
look up the server.
Fix this by looking up the server by address instead.
Don't get the epoch from a server, particularly one that we're looking up
by UUID, as UUIDs may be ambiguous and may map to more than one server - so
we can't draw any conclusions from it.

This struct is going to form the core of the operation management and is
