But I don't want to touch > the core library. Second update: .swap_activate is not implemented in the linux kernel for exfat and the commit causes EINVAL only for swap allocation. That is caused by bmap() due to the generic swap activation. So instead of working around the issue, we probably should have a feature in the kernel along with fallocate() support in exfat. Probably a kernel bug/missing feature. -- Andrea Cervesato SUSE QE Automation Engineer Linux andrea.cervesato@suse.com -- Mailing list info: https://lists.linux.it/listinfo/ltp
