net/sunrpc/pmap_clnt.c has been replaced by net/sunrpc/rpcb_clnt.c.

It is arguable whether NFSROOT will support IPv6, and thus whether
rpcb_getport_external needs to support rpcbind versions greater than 2.Signed-off-by: Chuck Lever

Eventually this interface will support versions 3 and 4 of the rpcbind
protocol, which will allow the Linux RPC server to register services on
IPv6 addresses.Signed-off-by: Chuck Lever

Now that we have a version of the portmapper that supports versions 3 and 4
of the rpcbind protocol, use it for new RPC client connections over
sockets.Signed-off-by: Chuck Lever
Signed-off-by: Trond Myklebust -
Introduce a replacement for the in-kernel portmapper client that supports
all 3 versions of the rpcbind protocol. This code is not used yet.Original code by Groupe Bull updated for the latest kernel, with multiple
bug fixes.Note that rpcb_clnt.c does not yet support registering via versions 3 and
4 of the rpcbind protocol. That is planned for a later patch.Signed-off-by: Chuck Lever

Currently rpc_malloc sets req->rq_buffer internally. Make this a more
generic interface: return a pointer to the new buffer (or NULL) and
make the caller set req->rq_buffer and req->rq_bufsize. This looks much
more like kmalloc and eliminates the side effects.To fix a potential deadlock, this patch also replaces GFP_NOFS with
GFP_NOWAIT in rpc_malloc. This prevents async RPCs from sleeping outside
the RPC's task scheduler while allocating their buffer.Signed-off-by: Chuck Lever
Signed-off-by: Trond Myklebust -
The RPC buffer size estimation logic in net/sunrpc/clnt.c always
significantly overestimates the requirements for the buffer size.
A little instrumentation demonstrated that in fact rpc_malloc was never
allocating the buffer from the mempool, but almost always called kmalloc.To compute the size of the RPC buffer more precisely, split p_bufsiz into
two fields; one for the argument size, and one for the result size.Then, compute the sum of the exact call and reply header sizes, and split
the RPC buffer precisely between the two. That should keep almost all RPC
buffers within the 2KiB buffer mempool limit.And, we can finally be rid of RPC_SLACK_SPACE!

NLM version 4 requests estimate the call and reply header sizes rather
conservatively, using the very maximum size allowed in the protocol even
though Linux always uses only a small fraction of the allowable space.Reduce the size of caller and lock arguments to conserve RPC buffer space
while XDR encoding NLM4 arguments. Add compile-time checks to ensure the
hostname string won't overflow NLM protocol maximums.Signed-off-by: Chuck Lever

Currently we do write coalescing in a very inefficient manner: one pass in
generic_writepages() in order to lock the pages for writing, then one pass
in nfs_flush_mapping() and/or nfs_sync_mapping_wait() in order to gather
the locked pages for coalescing into RPC requests of size "wsize".In fact, it turns out there is actually a deadlock possible here since we
only start I/O on the second pass. If the user signals the process while
we're in nfs_sync_mapping_wait(), for instance, then we may exit before
starting I/O on all the requests that have been queued up.Signed-off-by: Trond Myklebust
-
Do the coalescing of read requests into block sized requests at start of
I/O as we scan through the pages instead of going through a second pass.Signed-off-by: Trond Myklebust

It is redundant, and will interfere with the call to

The nfs statfs function returns a success code on error, and fills the

The Marvell IDE interface on my machine would hit a BUG_ON() in
lib/iomem.c because it was calling ata_pci_init_one() specifying just a
single port on the host, but that would actually end up trying to
initialize two ports, the second one with bogus information.This fixes "ata_pci_init_one()" so that it actually passes down the
n_ports variable that it got from the low-level driver to the host
allocation routine ("ata_host_alloc_pinfo()"), which results in the ATA
layer actually having the correct port number information.And in order to make it all work, I also needed to fix a few places that
had incorrectly hard-coded the fact that a host always had exactly two
ports (both ata_pci_init_bmdma() and ata_request_legacy_irqs() would
just always iterate over both ports).Acked-by: Jeff Garzik

This patch changes the docs and behaviour from "all states valid" to "no
states valid" if no .valid callback is assigned. Users of pm_ops that only
need mem sleep can assign pm_valid_only_mem without any overhead, others
will require more elaborate callbacks.Now that all users of pm_ops have a .valid callback this is a safe thing to
do and prevents things from getting messy again as they were before.Signed-off-by: Johannes Berg

Signed-off-by: Linus Torvalds -
Almost all users of pm_ops only support mem sleep, don't check in .valid and
don't reject any others in .prepare so users can be confused if they check
/sys/power/state, especially when new states are added (these would then
result in s-t-r although they're supposed to be something different).This patch implements a generic pm_valid_only_mem function that is then
exported for users and puts it to use in almost all existing pm_ops.Signed-off-by: Johannes Berg

This patch series cleans up some misconceptions about pm_ops. Some users of
the pm_ops structure attempt to use it to stop the user from entering suspend
to disk, this, however, is not possible since the user can always use
"shutdown" in /sys/power/disk and then the pm_ops are never invoked. Also,
platforms that don't support suspend to disk simply should not allow
configuring SOFTWARE_SUSPEND (read the help text on it, it only selects
suspend to disk and nothing else, all the other stuff depends on PM).The pm_ops structure is actually intended to provide a way to enter
platform-defined sleep states (currently supported states are "standby" and
"mem" (suspend to ram)) and additionally (if SOFTWARE_SUSPEND is configured)
allows a platform to support a platform specific way to enter low-power mode
once everything has been saved to disk. This is currently only used by ACPI
(S4).This patch:
The pm_ops.pm_disk_mode is used in totally bogus ways since nobody really
seems to understand what it actually does.This patch clarifies the pm_disk_mode description.
It also removes all the arm and sh users that think they can veto suspend to
disk via pm_ops; not so since the user can always do echo shutdown >
/sys/power/disk, they need to find a better way involving Kconfig or such.ACPI is the only user left with a non-zero pm_disk_mode.
The patch also sets the default mode to shutdown again, but when a new pm_ops
is registered its pm_disk_mode is selected as default, that way the default
stays for ACPI where it is apparently required.Signed-off-by: Johannes Berg

Today's print_symbol function dumps a kernel symbol with printk. This
patch extends the functionality of kallsyms.c so that the symbol lookup
function may be used without the printk. This is useful for modules that
want to dump symbols elsewhere, for example, to debugfs. I intend to use
the new function call in the GFS2 file system (which will be a separate
patch).[akpm@linux-foundation.org: build fix]
