Re: [PATCH v2 2/3] virt: tdx-guest: Add Quote generation support

How about the following?

Although this method reserves a fixed chunk of memory for GetQuote requests, such one-time allocation is preferable to the alternative choice of repeatedly allocating/freeing the shared buffer in the TDX_CMD_GET_QUOTE IOCTL handler, which will damage the direct map (because the sharing/unsharing process modifies the direct map). This allocation model is similar to that used by the AMD SEV guest driver.

Yes, this is clear, thank you.
