vflush

Declaration

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

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

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.
