*
* At least when compiled with debug, it would be useful if the
* free ICR call would fail if the in core representation has been
- * modified since the last serialize of clear callback.
- *
- * CLEAR: Pointer to the clear callback.
- *
- * In principle, there should be no need for the clear callback,
- * as the dirty flag should be maintained by the metadata cache.
- *.
- * However, some clients maintain dirty bits on internal data,
- * and we need some way of keeping these dirty bits in sync with
- * those maintained by the metadata cache. This callback exists
- * to serve this purpose. If defined, it is called whenever the
- * cache marks dirty entry clean, or when the cache is about to
- * discard a dirty entry without writing it to disk (This
- * happens as the result of an unprotect call with the
- * H5AC__DELETED_FLAG set, and the H5C__TAKE_OWNERSHIP_FLAG not
- * set.)
- *
- * Arguably, this functionality should be in the NOTIFY callback.
- * However, this callback is specific to only a few clients, and
- * it will be called relatively frequently. Hence it is made its
- * own callback to minimize overhead.
- *
- * The typedef for the clear callback is as follows:
- *
- * typedef herr_t (*H5C_clear_func_t)(const H5F_t *f,
- * void * thing,
- * hbool_t about_to_destroy);
- *
- * The parameters of the clear callback are as follows:
- *
- * f: File pointer.
- *
- * thing: Pointer to void containing the address of the in core
- * representation of the target metadata cache entry. This
- * is the same pointer that would be returned by a protect()
- * call of the associated addr and len.
- *
- * about_to_destroy: Boolean flag used to indicate whether the
- * metadata cache is about to destroy the target metadata
- * cache entry. The callback may use this flag to omit
- * operations that are irrelevant it the entry is about
- * to be destroyed.
- *
- * Processing in the clear function should proceed as follows:
- *
- * Reset all internal dirty bits in the target metadata cache entry.
- *
- * If the about_to_destroy flag is TRUE, the clear function may
- * ommit any dirty bit that will not trigger a sanity check failure
- * or otherwise cause problems in the subsequent free icr call.
- * In particular, the call must ensure that the free icr call will
- * not fail due to changes prior to this call, and after the
- * last serialize or clear call.
- *
- * If the function is successful, it must return SUCCEED.
- *
- * If it fails for any reason, the function must return FAIL and
- * push error information on the error stack with the error API
- * routines.
+ * modified since the last serialize callback.
*
* GET_FSF_SIZE: Pointer to the get file space free size callback.
