Subject: [edk2-devel] [PATCH v3 0/6] Support to unregister SMI handler in SMI
handlers
Months ago, I sent patch set to fix potential issues in the usage of SMI
handler unregistering SMI handler. Discussion can be found in below
link:
https://edk2.groups.io/g/devel/topic/103925794#114251
The conclusion was to only support SMI handler unregistering itself, and not
allow SMI handler unregistering other handlers, because we thought there would
be no such usage.
However, recently, I find in some platform, there is kind of usage.
To also support SMI handler unregistering other handlers, this patch set use a
totally different design. So I revert the former ones first to make the code
more readable.
Thank Laszlo for bring up the initial idea for the new design.
V2&V3:
Code refine based on Ray's comments
