Brian Behlendorf 21ade34764 Disable direct reclaim for z_wr_* threads ... The direct reclaim path in the z_wr_* threads must be disabled to ensure forward progress is always maintained for txg processing. This ensures that a txg will never get stuck waiting on itself because it entered the following memory reclaim callpath. ->prune_icache()->dispose_list()->zpl_clear_inode()->zfs_inactive() ->dmu_tx_assign()->dmu_tx_wait()->tgx_wait_open() It would be preferable to target this exact code path but the kernel offers no way to do this without custom patches. To avoid this we are forced to disable all reclaim for these threads. It should not be necessary to do this for other other z_* threads because they will not hold a txg open.
