pooka a96791040e remove unnecessary #ifdef 2010-05-11 20:21:56 +00:00
rmind 93deacb9f4 Remove mclpool_allocator, which is unnecessary since mb_map removal. 2010-04-16 02:57:15 +00:00
joerg 1476e7a45a Handle rump like the direct mapping case. 2010-02-08 22:55:36 +00:00
joerg d621e29eca Remove separate mb_map. The nmbclusters is computed at boot time based 
on the amount of physical memory and limited by NMBCLUSTERS if present.
Architectures without direct mapping also limit it based on the kmem_map
size, which is used as backing store. On i386 and ARM, the maximum KVA
used for mbuf clusters is limited to 64MB by default.

The old default limits and limits based on GATEWAY have been removed.
key_registered_sb_max is hard-wired to a value derived from 2048
clusters.

bouyer f8059f7e67 m_split0(): If the newly allocated mbuf holds only the header, 
don't forget to set m_len to 0. Otherwise whatever will compute the size
of this chain (including s_split() itself if called again on this chain)
will get it wrong, leading to various issues.

Bug exposed by the NFS server code with linux clients using TCP mounts.

thorpej 0cfa6e7487 Make the percpu API a little more friendly: 
- percpu_getptr() is now called percpu_getref() and implicitly disables
  preemption (via crit_enter()) when it is called.
- Added percpu_putref() which implicitly reenables preemption (via
  crit_exit()).

dogcow 55ddfc9aae change the MOWNER_INIT define to take two args; fix extant struct mowner 
decls to use it. Makes options MBUFTRACE compile again and not whinge about
missing structure declarations. (Also makes initialization consistent.)

yamt bd149b4812 m_copyback0: 
- unify two copies of code to extend a chain.
- when extending a chain,
	- use trailing space of the last mbuf if any.
	- use mbuf cluster if appropriate.

yamt 2e85eff671 - introduce M_MOVE_PKTHDR and use it where appropriate. 
intended to be mostly API compatible with openbsd/freebsd.
- remove a glue #define in netipsec/ipsec_osdep.h.

martin 71d020f371 Since we decided "const struct mbuf *" would not do the right thing (tm), 
remove ~all const from mbuf pointers.

tron a40b37b948 Change first argument of m_copydata() back to "struct mbuf *" because 
m_copydata() might eventually modify the "mbuf" structure to support
lazy mbuf mapping as pointed out by YAMAMOTO Takashi on "tech-net".

tron c4f68c0d95 Add missing RCS id. Problem pointed out by Jukka Salmi. 2005-06-02 12:58:16 +00:00

tron c54394a240 Change the first argument of m_copydata() to "const struct mbuf *" (which 
doesn't require any implementation changes). This will allow us to get
rid off a lot of nasty type casts.

the usage of MT_HEADER vs. MT_DATA is better defined and implemented.
