51 | * These zfs_log_* functions must be called within a dmu tx, in one |
52 | * of 2 contexts depending on zilog->z_replay: | |
53 | * | |
54 | * Non replay mode | |
55 | * --------------- | |
56 | * We need to record the transaction so that if it is committed to | |
57 | * the Intent Log then it can be replayed. An intent log transaction | |
58 | * structure (itx_t) is allocated and all the information necessary to | |
59 | * possibly replay the transaction is saved in it. The itx is then assigned | |
60 | * a sequence number and inserted in the in-memory list anchored in the zilog. | |
61 | * | |
62 | * Replay mode | |
63 | * ----------- | |
64 | * We need to mark the intent log record as replayed in the log header. | |
65 | * This is done in the same transaction as the replay so that they | |
66 | * commit atomically. | |
