Functions |
| void | dsl_dir_close (dsl_dir_t *dd, void *tag) |
| int | dsl_dir_open (const char *name, void *tag, dsl_dir_t **, const char **tail) |
| | Return the dsl_dir_t, and possibly the last component which couldn't be found in *tail.
|
| int | dsl_dir_open_spa (spa_t *spa, const char *name, void *tag, dsl_dir_t **, const char **tailp) |
| | same as dsl_open_dir, ignore the first component of name and use the spa instead
|
| int | dsl_dir_open_obj (dsl_pool_t *dp, uint64_t ddobj, const char *tail, void *tag, dsl_dir_t **) |
| void | dsl_dir_name (dsl_dir_t *dd, char *buf) |
| | buf must be long enough (MAXNAMELEN + strlen(MOS_DIR_NAME) + 1 should do)
|
| int | dsl_dir_namelen (dsl_dir_t *dd) |
| | Calculate name length, avoiding all the strcat calls of dsl_dir_name.
|
| uint64_t | dsl_dir_create_sync (dsl_pool_t *dp, dsl_dir_t *pds, const char *name, dmu_tx_t *tx) |
| void | dsl_dir_stats (dsl_dir_t *dd, nvlist_t *nv) |
| uint64_t | dsl_dir_space_available (dsl_dir_t *dd, dsl_dir_t *ancestor, int64_t delta, int ondiskonly) |
| | How much space would dd have available if ancestor had delta applied to it? If ondiskonly is set, we're only interested in what's on-disk, not estimated pending changes.
|
| void | dsl_dir_dirty (dsl_dir_t *dd, dmu_tx_t *tx) |
| void | dsl_dir_sync (dsl_dir_t *dd, dmu_tx_t *tx) |
| int | dsl_dir_tempreserve_space (dsl_dir_t *dd, uint64_t mem, uint64_t asize, uint64_t fsize, uint64_t usize, void **tr_cookiep, dmu_tx_t *tx) |
| | Reserve space in this dsl_dir, to be used in this tx's txg.
|
| void | dsl_dir_tempreserve_clear (void *tr_cookie, dmu_tx_t *tx) |
| | Clear a temporary reservation that we previously made with dsl_dir_tempreserve_space().
|
| void | dsl_dir_willuse_space (dsl_dir_t *dd, int64_t space, dmu_tx_t *tx) |
| | Call in open context when we think we're going to write/free space, eg.
|
| void | dsl_dir_diduse_space (dsl_dir_t *dd, dd_used_t type, int64_t used, int64_t compressed, int64_t uncompressed, dmu_tx_t *tx) |
| | call from syncing context when we actually write/free space for this dd
|
| void | dsl_dir_transfer_space (dsl_dir_t *dd, int64_t delta, dd_used_t oldtype, dd_used_t newtype, dmu_tx_t *tx) |
| int | dsl_dir_set_quota (const char *ddname, zprop_source_t source, uint64_t quota) |
| int | dsl_dir_set_reservation (const char *ddname, zprop_source_t source, uint64_t reservation) |
| int | dsl_dir_rename (dsl_dir_t *dd, const char *newname, int flags) |
| int | dsl_dir_transfer_possible (dsl_dir_t *sdd, dsl_dir_t *tdd, uint64_t space) |
| int | dsl_dir_set_reservation_check (void *arg1, void *arg2, dmu_tx_t *tx) |
| boolean_t | dsl_dir_is_clone (dsl_dir_t *dd) |
| void | dsl_dir_new_refreservation (dsl_dir_t *dd, struct dsl_dataset *ds, uint64_t reservation, cred_t *cr, dmu_tx_t *tx) |
| void | dsl_dir_snap_cmtime_update (dsl_dir_t *dd) |
| timestruc_t | dsl_dir_snap_cmtime (dsl_dir_t *dd) |
