There is no need for open files in /proc/sys/XXX to hold a reference count on
the module that provides the file to prevent module unload races. While there
is code active in the module p->used in the sysctl_table_header is
incremented, preventing the sysctl from being unregisted. Once the sysctl is
unregistered it cannot be found. Open files are also not a problem as they
revalidate the sysctl information and bump p->used before accessing module
code.So setting de->owner is unnecessary, makes for a bad example and gets in my
way of removing ctl_table->de.Signed-off-by: Eric W. Biederman

There has not been much maintenance on sysctl in years, and as a result is
there is a lot to do to allow future interesting work to happen, and being
ambitious I'm trying to do it all at once :)The patches in this series fall into several general categories.
- Removal of useless attempts to override the standard sysctls
- Registers of sysctl numbers in sysctl.h so someone else does not use
the magic number and conflict.- C99 conversions so it becomes possible to change the layout of
struct ctl_table without breaking everything.- Removal of useless claims of module ownership, in the proc dir entries
- Removal of sys_sysctl support where people had used conflicting sysctl
numbers. Trying to break glibc or other applications by changing the
ABI is not cool. 9 instances of this in the kernel seems a little
extreme.- General enhancements when I got the junk I could see out.
This patch:
Since x25 uses unique binary numbers inserting yourself at the head of the
search list for sysctls so you can override already registered sysctls is
pointless.Signed-off-by: Eric W. Biederman

After Al Viro (finally) succeeded in removing the sched.h #include in module.h
recently, it makes sense again to remove other superfluous sched.h includes.
There are quite a lot of files which include it but don't actually need
anything defined in there. Presumably these includes were once needed for
macros that used to live in sched.h, but moved to other header files in the
course of cleaning it up.To ease the pain, this time I did not fiddle with any header files and only
removed #includes from .c-files, which tend to cause less trouble.Compile tested against 2.6.20-rc2 and 2.6.20-rc2-mm2 (with offsets) on alpha,
arm, i386, ia64, mips, powerpc, and x86_64 with allnoconfig, defconfig,
allmodconfig, and allyesconfig as well as a few randconfigs on x86_64 and all
configs in arch/arm/configs on arm. I also checked that no new warnings were
introduced by the patch (actually, some warnings are removed that were emitted
by unnecessarily included header files).Signed-off-by: Tim Schmielau

AUTH_UNIX authentication (the standard with NFS) has a limit of 16 groups ids.
This causes problems for people in more than 16 groups.So allow the server to map a uid into a list of group ids based on local
knowledge rather depending on the (possibly truncated) list from the client.If there is no process on the server responding to upcalls, the gidlist in the
request will still be used.Signed-off-by: Neil Brown

Add support for using a filesystem UUID to identify and export point in the
filehandle.For NFSv2, this UUID is xor-ed down to 4 or 8 bytes so that it doesn't take up
too much room. For NFSv3+, we use the full 16 bytes, and possibly also a
64bit inode number for exports beneath the root of a filesystem.When generating an fsid to return in 'stat' information, use the UUID (hashed
down to size) if it is available and a small 'fsid' was not specifically
provided.Signed-off-by: Neil Brown

If we are using the same version/fsid as a current filehandle, then there is
no need to verify the the numbers are valid for this export, and they must be
(we used them to find this export).This allows us to simplify the fsid selection code.
Also change "ref_fh_version" and "ref_fh_fsid_type" to "version" and
"fsid_type", as the important thing isn't that they are the version/type of
the reference filehandle, but they are the chosen type for the new filehandle.And tidy up some indenting.

Most files in the 'nfsd' filesystem are transactional. When you write, a
reply is generated that can be read back only on the same 'file'.If the reply has zero length, the 'write' will incorrectly return a value of
'0' instead of the length that was written. This causes 'rpc.nfsd' to give an
annoying warning.This patch fixes the test.

Driver for the Atmel on-chip SPI master controller.
Tested primarily on AVR32/AT32AP7000/ATSTK1000 using mtd_dataflash and the
jffs2 filesystem. Should also work fine on various AT91 ARM-based chips
like AT91SAM926x and AT91RM9200.Hardware documentation can be found in the AT32AP7000 data sheet, or its
AT91 siblings, which can be downloaded fromhttp://www.atmel.com/dyn/products/datasheets.asp?family_id=682

Since serial devices are powered down when not in use and some of those
devices cannot be accessed when powered down, we need to enable power
around calls to get_mcrtl() when dumping port state via uart_line_info().
This resolves hangs observed on some machines while reading serial device
registers when a port is powered off.Signed-off-by: George G. Davis

The patch below works around a minor bug found in the UART of the remote
management card used in many HP ia64 and parisc servers (aka the Diva
UARTs). The problem is that the UART does not reassert the THRE interrupt
if it has been previously cleared and the IIR THRI bit is re-enabled. This
can produce a very annoying failure mode when used as a serial console,
allowing a boot/reboot to hang indefinitely until an RX interrupt kicks it
into working again (ie. an unattended reboot could stall).To solve this problem, a backup timer is introduced that runs alongside the
standard interrupt driven mechanism. This timer wakes up periodically,
checks for a hang condition and gets characters moving again. This backup
mechanism is only enabled if the UART is detected as having this problem,
so systems without these UARTs will have no additional overhead.This version of the patch incorporates previous comments from Pavel and
removes races in the bug detection code. The test is now done before the
irq linking to prevent races with interrupt handler clearing the THRE
interrupt. Short delays and syncs are also added to ensure the device is
able to update register state before the result is tested.Aristeu says:
this was tested on the following HP machines and solved the problem:
rx2600, rx2620, rx1600 and rx1620s.hpa says:
I have seen this same bug in soft UART IP from "a major vendor."
