How long do you plan to keep this workaround? Forever. In the ideal world we'll some day get around to restructuring all the xfstests that do tricky things with sub-500M filesystems, but that's the unfortunate part of removing support for small disks. Most of the fstests don't care about the fs size and so they'll run with the configured storage (some tens or millions of gigabytes) so we're mostly using the same fs sizes that users are expected to have. > LTP community: do we want to depend on this behavior or we just increase from 256MB to 301 MB > (either for XFS or for all).
