This fixes panic when listing sysctls on INVARIANTS-enabled kernel while having wbwd loaded. This panic was not fatal, at worst one additional space was printed. Also sbuf_trim() makes some sense even if drain function is set. The drain function is called only when buffer is to be expanded. So we could still trim existing buffer before drain is called. In this case it worked just fine - the trailing space was correctly trimmed. Obtained from: WHEEL Systems MFC after: 1 week |
