Most kernel builders have to touch their kernel source code anyway, why not also tell them to backport path_umount so even non-gki users can benefit from this? I know this might be a bit controversial as this will raise the barrier of entry, but the benefits are just so high. Idea was from OnlyTomInSecond on KernelSU group chat way back, and it has been on the discussions for some time references: https://t.me/KernelSU_group/27237/176515 https://t.me/KernelSU_group/3249/184908 https://github.com/tiann/KernelSU/discussions/955#discussioncomment-761716603d233db8bhttps://github.com/tiann/KernelSU/pull/1060 https://elixir.bootlin.com/linux/v5.9.1/source/fs/namespace.c#L1728 https://elixir.bootlin.com/linux/v5.10.9/source/fs/namespace.c#L1730 https://elixir.bootlin.com/linux/v6.5/source/fs/namespace.c#L1887 https://github.com/tiann/KernelSU/pull/1464#issuecomment-2002492107 Kernel side change examples 5.4961d9788624.19164917f56d4.14c07c70a0c54.9195f07593a4.421ea33fe41https://github.com/tiann/KernelSU/pull/1464#issuecomment-2002424069 ofcourse having someone on 3.18 confirm this will be nice. **PROS**: umount modules for everyone **CONS**: barrier of entry +1 --------- Co-authored-by: Christoph Hellwig <hch@lst.de> Co-authored-by: Fede2782 <78815152+Fede2782@users.noreply.github.com> Co-authored-by: Tom <31297720+onlytominsecond@users.noreply.github.com>
