Function Documentation

VirtioFsFuseForget()

EFI_STATUS VirtioFsFuseForget	(	IN OUT VIRTIO_FS *	VirtioFs,
		IN UINT64	NodeId
	)

Make the Virtio Filesysem device drop one reference count from a NodeId that the driver looked up by filename.

Send the FUSE_FORGET request to the Virtio Filesysem device for this. Unlike most other FUSE requests, FUSE_FORGET doesn't elicit a response, not even the common VIRTIO_FS_FUSE_RESPONSE header.

The function may only be called after VirtioFsFuseInitSession() returns successfully and before VirtioFsUninit() is called.

Parameters

[in,out]	VirtioFs	The Virtio Filesystem device to send the FUSE_FORGET request to. On output, the FUSE request counter "VirtioFs->RequestId" will have been incremented.
[in]	NodeId	The inode number that the client learned by way of lookup, and that the server should now un-reference exactly once.

Return values

EFI_SUCCESS

The FUSE_FORGET request has been submitted.

Returns

Error codes propagated from VirtioFsSgListsValidate(), VirtioFsFuseNewRequest(), VirtioFsSgListsSubmit().
