NAME

VFS_VGET - convert an inode number to a vnode

SYNOPSIS

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 **vpp

DESCRIPTION

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.
