Alexander Motin 5c32e9fcb2 Optimize kern.geom.conf* sysctls. ... On large systems those sysctls may generate megabytes of output. Before this change sbuf(9) code was resizing buffer by 4KB each time many times, generating tons of TLB shootdowns. Unfortunately in this case existing sbuf_new_for_sysctl() mechanism, supposed to help with this issue, is not applicable, since all the sbuf writes are done in different kernel thread. This change improves situation in two ways: - on first sysctl call, not providing any output buffer, it sets special sbuf drain function, just counting the data and so not needing big buffer; - on second sysctl call it uses as initial buffer size value saved on previous call, so that in most cases there will be no reallocation, unless GEOM topology changed significantly.
