Olivier Certner de6a4418ee sysctl(9): Ease exporting struct sizes; Discourage doing that ... Introduce two helpers, the more general SYSCTL_SIZEOF() and a struct-specific one SYSCTL_SIZEOF_STRUCT() which prepends 'struct' in the description and in the use of sizeof() but uses the raw structure name as the knob's name. The size of the object/structure is exported under 'debug.sizeof'. Existing knobs under 'debug.sizeof' were all converted to use the helpers. Add a note before the helpers discouraging the introduction of new leaves for ad-hoc reasons. List alternative means for developers to obtain the size of arbitrary kernel structures easily (thanks to markj@ for providing these). No functional change (intended).
