Andriy Gapon 3cf2ea1aea MFV r322236: 8126 ztest assertion failed in dbuf_dirty due to dn_nlevels changing ... illumos/illumos-gate@dcb6872c56 dcb6872c56 https://www.illumos.org/issues/8126 The sync thread is concurrently modifying dn_phys->dn_nlevels while dbuf_dirty() is trying to assert something about it, without holding the necessary lock. We need to move this assertion further down in the function, after we have acquired the dn_struct_rwlock.
