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#) 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
ffs_vget ();
in
sys/ufs/ffs/ffs_vfsops.c
for the canonical example.
