VFS_FHTOVP — turn an NFS filehandle into a vnode
VFS_FHTOVP(struct mount *mp, struct fid *fhp, struct vnode **vpp);
The VFS_FHTOVP() macro is used by the NFS server to turn an NFS
filehandle into a vnode.
The arguments it expects are:
mp The file system.
fhp The filehandle to convert.
vpp Return parameter for the new locked vnode.
The contents of the filehandle are defined by the file system and are not
examined by any other part of the system. It should contain enough
information to uniquely identify a file within the file system as well as
noticing when a file has been removed and the file system resources have
been reused for a new file. For instance, UFS file system stores the
inode number and inode generation counter in its filehandle.
A call to VFS_FHTOVP() should generally be preceded by a call to
VFS_CHECKEXP(9) to check if the file is accessible to the client.
The locked vnode for the file will be returned in *vpp.
