I find it's much more convenient to test out a kernel by running "kvm-xfstests smoke", or "kvm-xfstests full". BTW, I've found that the xfstests 74 test failure is very timing dependent. It doesn't fail when I use another system which has faster disks than dm-crypt'ed laptop drives, and where writeback mode is enabled with lots of memory available for caching purposes. It seems to require memory pressure and slower disks. I should check and see whether it involves ext4_writepage() getting invoked out of the direct reclaim path... - Ted -- To unsubscribe from this list: send the line "unsubscribe linux-ext4" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
