Let's update the list with the last file-systems that added support. You can easily verify this by "git grep FS_ALLOW_IDMAP" on the given Linux version to see that the fs is listed and then checkout the previous Linux version to see that it is not listed, therefore it was added in that version. Signed-off-by: Rodrigo Campos <rodrigo@xxxxxxxxxxx> --- I've took the liberty of adding hugetlbfs that was merged in Linux 6.9-rc1 but there is still no final release of 6.9. Please feel free to drop that if you prefer to wait for the final release to include it.
