* Replaced the misleading uses of a historical artefact M_TRYWAIT with M_WAIT.ru2008-03-251-14/+4
| | | | | | | | | | Removed dead code that assumed that M_TRYWAIT can return NULL; it's not true since the advent of MBUMA. Reviewed by: arch There are ongoing disputes as to whether we want to switch to directly using UMA flags M_WAITOK/M_NOWAIT for mbuf(9) allocation.

| | | | | | | | | | | | | | | | | | | | | | | | | | free function controlable, instead of passing the KVA of the buffer storage as the first argument. Fix all conventional users of the API to pass the KVA of the buffer as the first argument, to make this a no-op commit. Likely break the only non-convetional user of the API, after informing the relevant committer. Update the mbuf(9) manual page, which was already out of sync on this point. Bump __FreeBSD_version to 800016 as there is no way to tell how many arguments a CPP macro needs any other way. This paves the way for giving sendfile(9) a way to wait for the passed storage to have been accessed before returning. This does not affect the memory layout or size of mbufs. Parental oversight by: sam and rwatson. No MFC is anticipated.
