VFS_FHTOVP — turn
an NFS filehandle into a vnode
mount *mp, struct fid
*fhp, int flags,
struct vnode **vpp);
macro is used by the NFS server to turn an NFS filehandle into a vnode.
The arguments it expects are:
- The file system.
- The filehandle to convert.
- Additional locking flags to pass through to vget(9).
File systems are allowed to ignore flags and use
- 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.
The locked vnode for the file will be returned in *vpp.
