lstewart 2010-11-06 11:38:40 UTC FreeBSD src repository Modified files: (Branch: RELENG_7) share/man/man9 alq.9 sys/kern kern_alq.c sys/sys alq.h Log: SVN rev 214872 on 2010-11-06 11:38:40Z by lstewart MFC r207223: - Rework the underlying ALQ storage to be a circular buffer, which amongst other things allows variable length messages to be easily supported. - Extend KPI with alq_writen() and alq_getn() to support variable length messages, which is enabled at ALQ creation time depending on the arguments passed to alq_open(). Also add variants of alq_open() and alq_post() that accept a flags argument. The KPI is still fully backwards compatible and shouldn't require any change in ALQ consumers unless they wish to utilise the new features. - Introduce the ALQ_NOACTIVATE and ALQ_ORDERED flags to allow ALQ consumers to have more control over IO scheduling and resource acquisition respectively. - Strengthen invariants checking. - Document ALQ changes in ALQ(9) man page.
