Sorry to everyone involved, I've just sent the merge request - I wasn't much at computer in the past few weeks so wanted to wait until I got back home to send it just in case, as I didn't realize this was a recent regression that caused actual harm (it sounded like an old warning that someone just recently happened to hit, and sounded easy enough to work around locally if there is only one specific setup involved); I should have sent the fix separately or at least corrected myself about the schedule. > >>> It is causing regressions in my environment > >>> #regzbot introduced: 4c39529663b9 > > > > If anyone wonders, that is 4c39529663b931 ("slab: Warn on duplicate > > cache names when DEBUG_VM=y") [v6.12-rc1].

(that might have been nice to have as a Fixes tag for eventual backport, but at least that commit doesn't appear to have been picked up by stable so it's probably fine as is) Thanks, -- Dominique Martinet | Asmadeus
