Linus Torvalds 91b6163be4 sysctl changes for v6.10-rc1
Summary
 * Removed sentinel elements from ctl_table structs in kernel/*
 
   Removing sentinels in ctl_table arrays reduces the build time size and
   runtime memory consumed by ~64 bytes per array. Removals for net/, io_uring/,
   mm/, ipc/ and security/ are set to go into mainline through their respective
   subsystems making the next release the most likely place where the final
   series that removes the check for proc_name == NULL will land. This PR adds
   to removals already in arch/, drivers/ and fs/.
 
 * Adjusted ctl_table definitions and references to allow constification
 
   Adjustments:
     - Removing unused ctl_table function arguments
     - Moving non-const elements from ctl_table to ctl_table_header
     - Making ctl_table pointers const in ctl_table_root structure
 
   Making the static ctl_table structs const will increase safety by keeping the
   pointers to proc_handler functions in .rodata. Though no ctl_tables where
   made const in this PR, the ground work for making that possible has started
   with these changes sent by Thomas Weißschuh.
 
 Testing
 * These changes went into linux-next after v6.9-rc4; giving it a good month of
   testing.
