NAME
VFS_VGET - convert an inode number to a vnodeSYNOPSIS
In sys/param.h In sys/mount.h In sys/vnode.h Ft int Fn VFS_VGET struct mount *mp ino_t ino int flags struct vnode **vppDESCRIPTION
The Fn VFS_VGET looks up or creates a vnode from a (mount, inode#) tupple.Its arguments are:
- Fa mp
- The mount point.
- Fa ino
- The inode representing the file. This is a unique number assigned by the file system when vnodes are first created.
- Fa flags
- Additional locking flags to pass through to vget(9).
- Fa vpp
- Return parameter for the vnode.
This is an optional file system entry-point for file systems mainly intended for NFS server use, but many file systems use it internally in VOP_LOOKUP9 and similar.
If the file system does not support this call, then it should return Er EOPNOTSUPP .
Please see Fn ffs_vget in sys/ufs/ffs/ffs_vfsops.c for the canonical example.
