He asked for a immediate fix/revert, which did not happen, then he reverted on Oct 22.  After that point, this turned into a revert war.  Currently, the Oct 17 patch is in.

Here is a recap of a more detailed timeline before @PiJoules escalated the issue to @llvm/clang-area-team:
1. On Oct 17, I committed a patch to revert/rework a previous commit that caused a regression as reported in #160513. The regression was important enough that the fix got backported to the 21.x branch on Oct 20 and released in clang-format 21.1.4 the next day.
2. On Oct 21, @PiJoules reported a bug that appeared to be caused by my Oct 17 commit and asked for a fix or revert. No word "immediate" or similar was used in the request. (See https://github.com/llvm/llvm-project/pull/164048#issuecomment-3429630861.)
3. I responded about 9 hours later and pointed out that that commit was already backported to 21.1.4. I indicated that I would try to come up with a fix in a few days. In the same comment, I also notified the reviewer @HazardyKnusperkeks of the commit how we might want to proceed and got a positive reply right away.
4. PiJoules reverted the commit about 9 hours later, which was questioned by HazardyKnusperkeks as to why the urgency.
5. I reverted PiJoules's revert after my investigation which concluded that the bug @PiJoules reported was not caused by my Oct 17 commit, and asked PiJoules to file a bug report. (See #164866.)
