The problem is that it can't be merged until its prerequisites are merged. Andy Chiu's last patchset "riscv: support kernel-mode Vector" was 2 months ago, but he also gave a talk at Plumbers about it more recently (https://www.youtube.com/watch?v=eht3PccEn5o). So I assume he's still working on it. It sounds like he's also going to include support for preemption, and optimizations to memcpy, memset, memmove, and copy_{to,from}_user. I think it would be a good idea to split out the basic support for kernel_vector_{begin,end} so that the users of them, as well as the preemption support, can be considered and merged separately. Maybe patch 1 of the series (https://lore.kernel.org/r/20231019154552.23351-2-andy.chiu@xxxxxxxxxx) is all that's needed initially? Andy, what do you think? - Eric
