* Lock db_mtx around arc_release() in dbuf_release_bp() While this function is called only in sync context, the same buffer can be touched by dbuf_hold_impl() in open context, creating races. All other accesses to arc_release() are already protected by db_mtx, so just take it here too. Signed-off-by: Alexander Motin <alexander.motin@TrueNAS.com> * Lock db_mtx in sa_byteswap() While SA code seems protected by sa_lock, there is a back door of dmu_objset_userquota_get_ids(), that may hold and access the dbuf without sa_lock, relying only on db_mtx. Taking db_mtx here should protect both the arc_release() and the data for db_buf.
