It isn't really a network code. You just include <sys/epoch.h> which declares the epoch KPI and a few globally recognized epochs. For now the only one is the network epoch. If you want to have for a example a disk epoch also supported by interrupt code, that would add one extra declaration to epoch.h, and again nothing really disk related. -- Gleb Smirnoff _______________________________________________ svn-src-head@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/svn-src-head To unsubscribe, send any mail to "svn-src-head-unsubscr...@freebsd.org"
