Hi,
we received a bug report showing the regression on 6.13.1 kernel against 6.13.0. The symptom is that Chrome and VSCode stopped working with Gnome Scaling, as reported on openSUSE Tumbleweed bug tracker https://bugzilla.suse.com/show_bug.cgi?id=1236943
Quoting from there: """ I use the latest TW on Gnome with a 4K display and 150% scaling. Everything has been working fine, but recently both Chrome and VSCode (installed from official non-openSUSE channels) stopped working with Scaling. .... I am using VSCode with: `--enable-features=UseOzonePlatform --enable-features=WaylandWindowDecorations --ozone-platform-hint=auto` and for Chrome, I select `Preferred Ozone platform` == `Wayland`. """
Surprisingly, the bisection pointed to the backport of the commit b9b588f22a0c049a14885399e27625635ae6ef91 ("libfs: Use d_children list to iterate simple_offset directories").
Indeed, the revert of this patch on the latest 6.13.4 was confirmed to fix the issue. Also, the reporter verified that the latest 6.14-rc release is still affected, too.
For now I have no concrete idea how the patch could break the behavior of a graphical application like the above. Let us know if you need something for debugging. (Or at easiest, join to the bugzilla entry and ask there; or open another bug report at whatever you like.)
BTW, I'll be traveling tomorrow, so my reply will be delayed.
thanks,
Takashi
