Public bug reported: [Impact] CONFIG_AUFS_FS needs to be enabled in all kernels backported to Focal to keep compatibility when users upgrade kernels in the series. This kernel in particular did not have this config option enabled when the backport was created.
[Fix] Enable CONFIG_AUFS_FS and make sure it stays enabled on rebases. [Test case] * CONFIG_AUFS_FS and its related configs should be the same as the generic kernel in Focal. * The testcase ubuntu_aufs_smoke_test.aufs-smoke-test should be successful. [Regression potential] This is enabling a config option which was disabled before. Due to being intertwined with overlayfs and shiftfs changes in behavior or regressions could be cause on these two other filesystems. ** Affects: linux-lowlatency-hwe-5.15 (Ubuntu) Importance: Undecided Status: Invalid ** Affects: linux-lowlatency-hwe-5.15 (Ubuntu Focal) Importance: Undecided Status: Confirmed ** Also affects: linux-lowlatency-hwe-5.15 (Ubuntu Focal) Importance: Undecided Status: New ** Changed in: linux-lowlatency-hwe-5.15 (Ubuntu) Status: New => Invalid ** Changed in: linux-lowlatency-hwe-5.15 (Ubuntu Focal) Status: New => Confirmed -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-lowlatency-hwe-5.15 in Ubuntu. https://bugs.launchpad.net/bugs/1981203 Title: Enable AUFS in focal/linux-lowlatency-hwe-5.15 Status in linux-lowlatency-hwe-5.15 package in Ubuntu: Invalid Status in linux-lowlatency-hwe-5.15 source package in Focal: Confirmed Bug description: [Impact] CONFIG_AUFS_FS needs to be enabled in all kernels backported to Focal to keep compatibility when users upgrade kernels in the series.
