* Convert pcbinfo and inpcb mutexes to rwlocks, and modify macros toRobert Watson2008-04-171-2/+2
| | | | | | | | | | | | | | | | | | explicitly select write locking for all use of the inpcb mutex. Update some pcbinfo lock assertions to assert locked rather than write-locked, although in practice almost all uses of the pcbinfo rwlock main exclusive, and all instances of inpcb lock acquisition are exclusive. This change should introduce (ideally) little functional change. However, it lays the groundwork for significantly increased parallelism in the TCP/IP code.

* Give MEXTADD() another argument to make both void pointers to thePoul-Henning Kamp2008-02-011-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. Notes: svn path=/head/; revision=175872
