# vflush

Reclaim the vnodes for a mount.

## Declaration

```occ
int vflush(struct mount *mp, struct vnode *skipvp, int flags);
```

## Parameters

- `mp`: The mount with the vnodes to terminate.
- `skipvp`: A specific vnode to not reclaim or to let interrupt an unforced flush.
- `flags`: Controls that indicate how to handle vnodes.

## Return Value

Return Value 0 for success, EBUSY if vnodes were busy and FORCECLOSE was not set.

## Discussion

Discussion This function is used to clear out the vnodes associated with a mount as part of the unmount process. Its parameters can determine which vnodes to skip in the process and whether in-use vnodes should be forcibly reclaimed. File systems should call this function from their unmount code, because VFS code will always call it with SKIPROOT | SKIPSWAP | SKIPSYSTEM; file systems must take care of such vnodes themselves.
