Most of these links weaken your claim rather than support it. The lkml links are patch submissions in a _development_ discussion, not ordinary users running a stable distro. The f2fs bugzilla links are the same issue we already discussed, a regression in the brand-new 6.9 kernel released only days earlier, with the fix landing in 6.9.3. The suse bug is an upstream e2fsprogs issue. This is precisely the kind of issue distro package maintainers can catch, patch, or avoid before it reaches ordinary users on a stable release. The launchpad link is another development discussion, not an example of ordinary users experiencing a bug in a stable release.

Linux does experience regressions, but your argument conflates upstream development, bleeding edge releases, and stable distro releases. Those distinctions are fundamental to how linux distributions work, and these links don't support the claim you're making.

Yep. Good catch, I think you win the argument. These are all distros that are under development and their underlying issues should never be called-out as handing the user frustration as they willingly chose to become a victim of the kernel.
