These patches have landed in v4.5rc3 squashed as 65376df582174ffcec9e6471bf5b0dd79ba05e4a (v4.5-rc3~15^2~9). Is that sufficient, or should I reping once 4.5 final is out? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1547231 Title: /proc/$pid/maps performance regression To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1547231/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
