Author: bdrewery Date: Sat Mar 22 10:26:09 2014 New Revision: 263620 URL: http://svnweb.freebsd.org/changeset/base/263620 Log: Rename global cnt to vm_cnt to avoid shadowing. To reduce the diff struct pcu.cnt field was not renamed, so PCPU_OP(cnt.field) is still used. pc_cnt and pcpu are also used in kvm(3) and vmstat(8). The goal was to not affect externally used KPI. Bump __FreeBSD_version_ in case some out-of-tree module/code relies on the the global cnt variable. Exp-run revealed no ports using it directly.
