- * Similar to bioset_create(), but initializes a passed-in bioset instead of

+ * Description:
+ * Set up a bio_set to be used with @bio_alloc_bioset. Allows the caller

+ * Front pad allocation is useful for embedding the bio inside

+ * 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.
