            Bug ID: 211315
           Summary: [aarch64][xfstests/ext3 generic/472] swapon: Invalid
                    argument
           Product: File System
           Version: 2.5
    Kernel Version: 5.11.0-0.rc4.20210120git45dfb8a5659a.131.eln108.aarch6
                    4
          Hardware: ARM
                OS: Linux
              Tree: Mainline
            Status: NEW
          Severity: normal
          Priority: P1
         Component: ext3
          Assignee: fs_ext3@kernel-bugs.osdl.org
          Reporter: neolorry+bugzilla.kernel.org@googlemail.com
        Regression: No

xfstests generic/472 fails on ext3 on the latest kernel
(kernel-5.11.0-0.rc4.20210120git45dfb8a5659a.131.eln108.aarch64 from
https://koji.fedoraproject.org/koji/buildinfo?buildID=1671933). This only
happens on aarch64 and ext3 with 2048 block size. I can reproduce it on
kernel-4.18 based RHEL-8 kernel as well.
