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.
