If they are not ready to send to list, you can send to me, I would like= to test. I tested this patchset for kvm guest image cleanup. Host ext4 + guest ext4 guest side use lukas's fstrim tool, host side use a modified version of Christoph's qemu block discard patch there's many error like following: [62834.936374] EXT4-fs error (device sda7): ext4_ext_lookup_hole:2907: inode #1310744: comm qemu-system-x86: bad header/extent: invalid magic - magic 0, entries 0, max 256(0), depth 256(0) [62834.936616] EXT4-fs error (device sda7): ext4_ext_lookup_hole:2907: inode #1310744: comm qemu-system-x86: bad header/extent: invalid magic - magic 0, entries 0, max 256(0), depth 256(0) bad header/extent: invalid magic - magic 0, entries 0, max 256(0), dept= h 256(0) Then host pc hangs there. BTW, host xfs + guest ext4 works well for me. -- Thanks Dave -- To unsubscribe from this list: send the line "unsubscribe linux-ext4" i= n the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
