nfsrv_rename() can exit without calling genfs_renamelock_exit() because
the nfsm_reply() can do return (0) on error.
Change nfsm_reply to use 'error = 0; goto nfsmout' instead.
Fix a few place so it's safe to goto nfsmout from nfsm_reply, or other
macros calling it.
As a side effect it could fix a missing vrele(dirp) in various place where
nfsm_reply could return(0).
- struct timeval time is gone
time.tv_sec -> time_second
- struct timeval mono_time is gone
mono_time.tv_sec -> time_uptime
- access to time via
{get,}{micro,nano,bin}time()
get* versions are fast but less precise
- support NTP nanokernel implementation (NTP API 4)

be inserted into ktrace records. The general change has been to replace
"struct proc *" with "struct lwp *" in various function prototypes, pass
the lwp through and use l_proc to get the process pointer when needed.
Bump the kernel rev up to 1.6V
- for READ procedure, don't send back more bytes than requested.
- don't have doubtful assumptions on mbuf chain structure.
- rename a function (nfsm_adj -> nfs_zeropad) to avoid confusion as
the semantics of the function was changed.
instead of "struct vnode". This saves a number of pointer dereferences;
it sums up to about half a kB for me. And it paves the way for future
fixes.
While cleaning up, eliminate a write-only member of "struct nfsreq"
and a pointless assignment in the NFS_V2_ONLY case.
Do a little mbuf rework while here. Change all uses of MGET*(*, M_WAIT, *)
to m_get*(M_WAIT, *). These are not performance critical and making them
call m_get saves considerable space. Add m_clget analogue of MCLGET and
make corresponding change for M_WAIT uses.
Modify netinet, gem, fxp, tulip, nfs to support MBUFTRACE.
Begin to change netstat to use sysctl.
add a flag that specify if the file can be truncated safely or not
to nfsm_loadattr and friends. when it isn't safe, just mark the nfsnode
as "should be truncated later".
ok'ed by Frank van der Linden and Chuck Silvers.
close kern/18036.
set via NFSV3SATTRTIME_TOSERVER and not NFSV3SATTRTIME_TOCLIENT,
add VA_UTIMES_NULL to the va_vflags. This reflects our policy
where we're much more liberal about who can set a & m times to 'now'
than we are about who can set them to a specific time.
Should close PR 15597 from Martin Husemann. Patch is based on the
one Matthias Drochner gave in the PR.
In readdirplus, don't keep such pointers but store the file attributes
in a variable instead until they are needed. Change nfsm_loadattr*
a bit so it can accept a direct pointer to an nfs_fattr structure.

Make nfs_realign go away on sparc and add functionality to nfsm_disct.

[XXX this introduces an ifdef __i386__, see the comment. Should be changed]
struct member cn_nameptr 'const', since they should never be used to
modify the path name. (Only the pathname buffer, cn_pnbuf, should be
modified.) Propagate the const poisoning to code that uses the namei
and componentname structs.
