That seems fine to me. This is all during runtime only, and doesn't change ondisk format at all right? >> 2/ any really old software not built with LFS support may start failing >> stat() calls with -EOVERFLOW on inode numbers >2^32.

Also note the https://lintian.debian.org/tags/binary-file-built-without-LFS- support.html It may have been better to scope the patch for backport to s390x only, however, given that hwe kernels will have this eventually, imho it is fine to submit this. Btw, you can also submit kernel patch to the kernel-team mailing list, if it is formatted as per Ubuntu Kernel team guidelines with like BugLink: https://bugs.launchpad.net/bugs/1899582. Note we are past kernel freeze now, and there is no SRU cycle between now and 8th of November, due to datacenter move as announced in https://lists.ubuntu.com/archives/kernel-sru- announce/2020-September/000170.html Hence the earlier this can land is probably December. -- 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/1899582 Title: ceph: fix inode number handling on arches with 32-bit ino_t Status in Ubuntu on IBM z Systems: Triaged Status in linux package in Ubuntu: New Status in linux source package in Focal: New Status in linux source package in Groovy: New Bug description: Backport provided for git-commit to 20.04 kernel. https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=ebce3eb2f7ef9f6ef01a60874ebd232450107c9a Backport patch attached for commit ebce3eb upstream.
