Public bug reported: SRU Justification
Impact: Shiftfs does not mark it's slab cache as reclaimable. While this is not a big deal it is not nice to the kernel in general. The shiftfs cache is not so important that it can't be reclaimed. Regression Potential: Limited to shiftfs. This patch has been tested for multiple days and has not caused any regressions. Test Case: Open a lot of files in shiftfs to get them into the cache and then cause memory pressure via e.g. stress-ng and see if the shiftfs cache shrinks. Target Kernels: All LTS kernels with shiftfs support. ** Affects: linux (Ubuntu) Importance: Undecided Assignee: Christian Brauner (cbrauner) Status: In Progress ** Changed in: linux (Ubuntu) Status: New => In Progress ** Changed in: linux (Ubuntu) Assignee: (unassigned) => Christian Brauner (cbrauner) -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1842059 Title: shiftfs: mark kmem_cache as reclaimable Status in linux package in Ubuntu: In Progress Bug description: SRU Justification Impact: Shiftfs does not mark it's slab cache as reclaimable.
