Module name: mbuf
Committed by: pcahyna
Date: Tue Aug 8 10:03:14 UTC 2006
Modified Files:
mbuf/userland/mbuf_impl: uipc_mbuf.c uipc_mbuf2.c
mbuf/userland/mbuf_impl/sys: mbuf.h
Log Message:
Add m_datarange and m_datarange_rw functions, which correspond to
mptr_pullup and mptr_rw macros, but without the sizeof magic - they accept
an explicit "len" argument.
Rename some flags to the m_pulldown0 internal function and add new flags
to request blocking allocation, alignment and leading space in a newly
allocated mbuf. (The intent is to duplicate the functionality of m_copyup.)
The new functions accept those flags, too.
Change the semantics of mptr a bit - now it assumes that all the data are
in the first mbuf, even in the case ofa nonzero offset.
Revert to upstream version 1.110 of uipc_mbuf.c, this is what corresponds
to my kernel snapshot.
