Linus Torvalds f8a8b94d06 sysctl changes for 6.11-rc1
Summary
 
 * Remove "->procname == NULL" check when iterating through sysctl table arrays
 
     Removing sentinels in ctl_table arrays reduces the build time size and
     runtime memory consumed by ~64 bytes per array. With all ctl_table
     sentinels gone, the additional check for ->procname == NULL that worked in
     tandem with the ARRAY_SIZE to calculate the size of the ctl_table arrays is
     no longer needed and has been removed. The sysctl register functions now
     returns an error if a sentinel is used.
 
 * Preparation patches for sysctl constification
 
     Constifying ctl_table structs prevents the modification of proc_handler
     function pointers as they would reside in .rodata. The ctl_table arguments
     in sysctl utility functions are const qualified in preparation for a future
     treewide proc_handler argument constification commit.
 
 * Misc fixes
 
     Increase robustness of set_ownership by providing sane default ownership
     values in case the callee doesn't set them. Bound check proc_dou8vec_minmax
     to avoid loading buggy modules and give sysctl testing module a name to
     avoid compiler complaints.
 
 Testing
 
   * This got push to linux-next in v6.10-rc2, so it has had more than a month
     of testing

Pull sysctl updates from Joel Granados:

 - Remove "->procname == NULL" check when iterating through sysctl table
   arrays

   Removing sentinels in ctl_table arrays reduces the build time size
   and runtime memory consumed by ~64 bytes per array. With all
   ctl_table sentinels gone, the additional check for ->procname == NULL
   that worked in tandem with the ARRAY_SIZE to calculate the size of
   the ctl_table arrays is no longer needed and has been removed. The
   sysctl register functions now returns an error if a sentinel is used.

 - Preparation patches for sysctl constification

   Constifying ctl_table structs prevents the modification of
   proc_handler function pointers as they would reside in .rodata. The
   ctl_table arguments in sysctl utility functions are const qualified
   in preparation for a future treewide proc_handler argument
   constification commit.

 - Misc fixes

   Increase robustness of set_ownership by providing sane default
   ownership values in case the callee doesn't set them. Bound check
   proc_dou8vec_minmax to avoid loading buggy modules and give sysctl
   testing module a name to avoid compiler complaints.
