Description

In the osd_declare_xattr_set() for ldiskfs:

        if (strcmp(name, XATTR_NAME_VERSION) == 0) {
                /* no credits for version */
                return 0;
        }

So if a caller calls only dt_version_set() to set inode version, the reserved credits for this transaction will be zero. I think we'd reserve 1 block for version set.
