There are currently no users in the kernel for CTL_ANY and it only has effect on the binary interface which is practically unused. So this complicates sysctl lookups for no good reason so just remove it. Signed-off-by:

binfmt_misc has a mount point in the middle of the sysctl and that mount point is created as a proc_generic directory. Doing it that way gets in the way of cleaning up the sysctl proc support as it continues the existence of a horrible hack. So instead simply create the directory as an ordinary sysctl directory. At least that removes the magic special case. [akpm@osdl.org: warning fix] Signed-off-by:

This is just a simple cleanup to keep kernel/sysctl.c from getting to crowded with special cases, and by keeping all of the ipc logic to together it makes the code a little more readable. [gcoady.lk@gmail.com: build fix] Signed-off-by:

ocfs2 was did not have the binary number it uses under CTL_FS registered in sysctl.h. Register it to avoid future conflicts, and change the name of the definition to be in line with the rest of the sysctl numbers. Signed-off-by:

Will converting the coda sysctl initializers I discovered that it is yet another user of sysctl that was stomping CTL_KERN. So off with it's sys_sysctl support since it wasn't done in a supportable way. Signed-off-by:

The real time clock driver was using the binary number reserved for cdroms in the sysctl binary number interface, which is a no-no. So since the sysctl binary interface is wrong remove it. Signed-off-by:

In the binary sysctl interface the hpet driver was claiming to be the cdrom driver. This is a no-no so remove support for the binary interface. Signed-off-by:

Basically everything was done but I removed all element initializers from the trailing entries to make it clear the entire last entry should be zero filled. Signed-off-by:

While doing the C99 conversion I notices that the top level sh64 directory was using the binary number for CTL_KERN. That is a no-no so I removed the support for the sysctl binary interface only leaving sysctl /proc support. At least the sysctl tables were placed at the end of the list so user space did not see this mistake. Signed-off-by:

We need to have the the definition of all top level sysctl directories registers in sysctl.h so we don't conflict by accident and cause abi problems. Signed-off-by:

While C99 converting the ctl_table initializers I realized that the binary sysctl numbers were in conflict with the binary values under CTL_KERN. Including CTL_KERN KERN_VERSION as used by glibc. So I just removed the sysctl binary interface for these values, as it was unsupportable. Luckily these sysctl were inserted at the end of the sysctl list so this bug was not visible to userspace.

The assignment of binary numbers for sys_sysctl use was in shambles and despite requiring methods. Nothing was implemented on the sys_sysctl side. So this patch gives a mercy killing to the sys_sysctl support for powermanagment on mips/au1000. Signed-off-by:

This convters the sysctl ctl_tables to use C99 initializers. While I was looking at it I discovered it was using a portion of the sysctl binary addresses space under CTL_KERN KERN_OSTYPE which was completely inappropriate. So I completely removed all of the sysctl binary names, to remove and avoid the ABI conflict. Signed-off-by:

By not using the enumeration in sysctl.h (or even understanding it) the SN platform placed their arch specific xpc directory on top of CTL_KERN and only because they didn't have 4 entries in their xpc directory got lucky and didn't break glibc. This is totally irresponsible. So this patch entirely removes sys_sysctl support from their sysctl code. Hopefully they don't have ascii name conflicts as well. And now that they have no ABI numbers add them to the end instead of the sysctl list instead of the head so nothing else will be overridden. Cc: Tony Luck <tony.luck@intel.com> Signed-off-by:

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:
