All ctl_table declared outside of functions and that remain unmodified after
initialization are const qualified. This prevents unintended modifications to
proc_handler function pointers by placing them in the .rodata section. This is
a continuation of the tree-wide effort started a few releases ago with the
constification of the ctl_table struct arguments in the sysctl API done in
78eb4ea25cd5 ("sysctl: treewide: constify the ctl_table argument of
proc_handlers")
Testing:
Testing was done on 0-day and sysctl selftests in x86_64. The linux-next
branch was not used for such a big change in order to avoid unnecessary merge
conflicts
