The "sysctl: Remove the end element in sysctl table arrays" commit is the one that actually removes the empty element. With a "yesall" configuration the bloat-o-meter says that 9158 bytes where saved (report at the end of the cover letter). Main changes: 1. Add the ctl_table size into the ctl_table_header 2. Remove the empty element at the end of all ctl_table arrays Commit Overview: 1. There are preparation commits that make sure that we have the ctl_table_header in all the places that we need to have the array size. sysctl: Prefer ctl_table_header in proc_sysct sysctl: Use the ctl header in list ctl_table macro sysctl: Add ctl_table_size to ctl_table_header 2. Add size to relevant register calls. Calculate the ctl_table array size where register_sysctl is called. Add a table_size argument to the relevant sysctl register functions (init_header, __register_sysctl_table, register_net_sysctl, register_sysctl and register_sysctl_init). Important to note that these commits do NOT change the way we calculate size; they plumb things in preparation for the empty element removal commit. Care is taken to leave the tree in a state where it can be compiled which is the reason to not separate the "big" commits (like "sysctl: Add size to the register_net_sysctl function"). If you have an alternative way of dealing with such a big commit while leaving it in a compilable state, please let me know. sysctl: Add size argument to init_header sysctl: Add a size arg to __register_sysctl_table sysctl: Add size to the register_net_sysctl function sysctl: Add size to register_sysctl sysctl: Add size to register_sysctl_init 3. Do the final empty element remove. This commit both removes the empty final element from the ctl_table array and switches to managing array size with the ctl_table_header size. This is also a "big" commit; please get back to me if you have an alternate way of handling it. sysctl: Remove the end element in sysctl table arrays 4. Clean things up by removing things that no longer make sense logically. sysctl: Remove nr_entries from new_links sysctl: rm "child" from __register_sysctl_table doc Additional Comments: 1. Still waiting on 0-day to tell me what I missed. Will address any issues in a V2 if necessary. 2. @mcgrof: let me know if you have any way of making the big commits a bit more digestible. You have done some of these big patches before and maybe you have a trick that make reviewing easier.
