Igor Lvovsky 478d64fdae Add additional state TXG_STATE_WAIT_FOR_SYNC for txg. ... In several cases when digging into kstats we can found two txgs in SYNC state, e.g. txg birth state nreserved nread nwritten ... 985452 258127184872561 C 0 373948416 2376272384 ... 985453 258129016180616 C 0 378173440 28793344 ... 985454 258129016271523 S 0 0 0 ... 985455 258130864245986 S 0 0 0 ... 985456 258130867458851 O 0 0 0 ... However only first txg (985454) is really syncing at this moment. The other one (985455) marked as SYNCED is actually in a post-QUIESCED state and waiting to start sync. So, the new TXG_STATE_WAIT_FOR_SYNC state between TXG_STATE_QUIESCED and TXG_STATE_SYNCED was added to reveal this situation. txg birth state nreserved nread nwritten ... 1086896 235261068743969 C 0 163577856 8437248 ... 1086897 235262870830801 C 0 280625152 822594048 ... 1086898 235264172219064 S 0 0 0 ... 1086899 235264936134407 W 0 0 0 ... 1086900 235264936296156 O 0 0 0 ...
