The compression INCOMPAT flags are generally checked and updated in the open_ctree() function. But, on remount, open_ctree() is not called. I was going to test a patch to update the INCOMPAT flags similar to the way lzo INCOMPAT is updated when specifying the compress method in defragmentation. http://kerneltrap.org/mailarchive/linux-btrfs/2010/11/18/6886194 But, let me know if it is preferred to just return -EINVAL when trying to remount with a compression method that has an INCOMPAT not yet seen by that volume. -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
