* bioset_init - Initialize a bio_set
+ * @bs: pool to initialize
* @pool_size: Number of bio and bio_vecs to cache in the mempool

* @flags: Flags to modify behavior, currently %BIOSET_NEED_BVECS

*
- * Similar to bioset_create(), but initializes a passed-in bioset instead of
- * separately allocating it.
+ * Description:
+ * Set up a bio_set to be used with @bio_alloc_bioset. Allows the caller
+ * to ask for a number of bytes to be allocated in front of the bio.
+ * Front pad allocation is useful for embedding the bio inside
+ * another structure, to avoid allocating extra data to go with the bio.
+ * Note that the bio must be embedded at the END of that structure always,
+ * or things will break badly.
+ * If %BIOSET_NEED_BVECS is set in @flags, a separate pool will be allocated
+ * for allocating iovecs. This pool is not needed e.g. for bio_clone_fast().
+ * If %BIOSET_NEED_RESCUER is set, a workqueue is created which can be used to
+ * dispatch queued requests when the mempool runs out of space.
