From 7526aa54b261087014bdea7e361f900d4741c35e Mon Sep 17 00:00:00 2001 From: Will Deacon Date: Mon, 3 Sep 2018 15:19:37 +0100 Subject: MAINTAINERS: Add entry for MMU GATHER AND TLB INVALIDATION We recently had to debug a TLB invalidation problem on the munmap() path, which was made more difficult than necessary because: (a) The MMU gather code had changed without people realising (b) Many people subtly misunderstood the operation of the MMU gather code and its interactions with RCU and arch-specific TLB invalidation (c) Untangling the intended behaviour involved educated guesswork and plenty of discussion Hopefully, we can avoid getting into this mess again by designating a cross-arch group of people to look after this code. It is not intended that they will have a separate tree, but they at least provide a point of contact for anybody working in this area and can co-ordinate any proposed future changes to the internal API.
