- Make getvfsbyname() take a struct xvfsconf *.
- Convert several consumers of getvfsbyname() to use struct xvfsconf.
- Correct the getvfsbyname.3 manpage.
- Create a new vfs.conflist sysctl to dump all the struct xvfsconf in the
kernel, and rewrite getvfsbyname() to use this instead of the weird
existing API.
- Convert some {set,get,end}vfsent() consumers to use the new vfs.conflist
sysctl.
- Convert a vfsload() call in nfsiod.c to kldload() and remove the useless
vfsisloadable() and endvfsent() calls.
- Add a warning printf() in vfs_sysctl() to tell people they are using
an old userland.
After these changes, it's possible to modify struct vfsconf without
breaking the binary compatibility. Please note that these changes don't
break this compatibility either.
When bp will have updated mount_smbfs(8) with the patch I sent him, there
will be no more consumers of the {set,get,end}vfsent(), vfsisloadable()
and vfsload() API, and I will promptly delete it.

asynchronous I/O server
|
|
.Sh SYNOPSIS
|
|
.Nm
|
|
.Op Fl n Ar num_servers
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
utility is a kernel process which run on an
|
|
.Tn NFS
|
|
client machine to service asynchronous I/O requests to its server.
|
|
It improves performance but is not required for correct operation.
|
|
.Pp
|
|
This program controls the maximum number of processes that the kernel runs.
|
|
.Pp
|
|
The options are as follows:
|
|
.Bl -tag -width indent
|
|
.It Fl n
|
|
Specify how many servers are permitted to be started.
|
|
.El
|
|
.Pp
|
|
A client should run enough daemons to handle its maximum
|
|
level of concurrency, typically four to six.
|
|
.Pp
|
|
If
|
|
.Nm
|
|
detects that the running kernel does not include
|
|
.Tn NFS
|
|
support, it will attempt to load a loadable kernel module containing
|
|
.Tn NFS
|
|
code, using
|
|
.Xr kldload 2 .
|
|
If this fails, or no
|
|
.Tn NFS
|
|
KLD was available,
|
|
.Nm
|
|
exits with an error.
