This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed- focal' to 'verification-done-focal'. If the problem still exists, change the tag 'verification-needed-focal' to 'verification-failed-focal'.
If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed.

A fix hasn't been identified yet, however, reverting commit "mm/slub: fix a memory leak in sysfs_slab_add()", upstream dde3c6b72a16c2db826f54b2d49bdea26c3534a2, applied to focal/linux as part of v5.4.47 upstream stable release (bug 1884089), seems to improve the situation. [ Fix ] I propose to revert commit "mm/slub: fix a memory leak in sysfs_slab_add()" while we don't find a better fix for it. [ Test Case ] Please see bug 1894780. [ Regression potential ] The commit being reverted fixes a memory leak from a 2015 commit, so the chances of reverting it introducing more regressions is low. However, if it does we can expect issues on the sysfs slab code during memory allocations.
