hello ted: many thanks for your xfstests-bld project which can be deployed on android systems and make mobile phone more robust and stable. but as is known, many low-end mobile phone’s cpu still use the arm32 architecture. and if these low-end mobile phone also can make full use of xfstests to do fs tests, there will be more fs bug will be found and our filesystem will become more robust. but from below link: https://www.kernel.org/pub/linux/kernel/people/tytso/kvm-xfstests there is not arm32 root_fs. so if you or anyone can offer me a link which can download arm32 root_fs needed by xfstests, i appreciate it very much. best regards.
