This is the current draft of my filesystem manpages. Some files are incomplete and some are just placeholders but I wanted to try to get something at least into 2.2 on the grounds that what I have is a lot better than nothing. I also wanted to commit something which documents the interfaces in 2.2 before I start updating the documentation for 3.0. This is a definite 2.2 candidate and is also relavent to 2.1 if people still care about that branch.

This is used by the NFS server to turn an NFS filehandle into a vnode.

The filesystem.
.It Ar fhp
The filehandle to convert.
.It Ar vpp
Return parameter for the new locked vnode.
.El
.Pp
The contents of the filehandle are defined by the filesystem and are
not examined by any other part of the system. It should contain
enough information to uniquely identify a file within the filesystem
as well as noticing when a file has been removed and the filesystem
resources have been reused for a new file. For instance, UFS
filesystem stores the inode number and inode generation counter in its
filehandle.
