NAME
VFS_VGET — convert an inode number to a vnodeSYNOPSIS
#include < sys/param.h>#include < sys/mount.h>
#include < sys/vnode.h>
int
VFS_VGET( struct mount *mp, ino_t ino, int flags, struct vnode **vpp);
DESCRIPTION
The VFS_VGET() looks up or creates a vnode from a (mount, inode#) tuple.Its arguments are:
- mp
- The mount point.
- ino
- The inode representing the file. This is a unique number assigned by the file system when vnodes are first created.
- flags
- Additional locking flags to pass through to vget(9).
- 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_LOOKUP(9) and similar.
If the file system does not support this call, then it should return EOPNOTSUPP.
Please see ffs_vget() in sys/ufs/ffs/ffs_vfsops.c for the canonical example.
