From bf800ef1816b4283a885e55ad38068aec9711e4d Mon Sep 17 00:00:00 2001 From: Kent Overstreet Date: Thu, 6 Sep 2012 15:35:02 -0700 Subject: block: Add bio_clone_bioset(), bio_clone_kmalloc() Previously, there was bio_clone() but it only allocated from the fs bio set; as a result various users were open coding it and using __bio_clone(). This changes bio_clone() to become bio_clone_bioset(), and then we add bio_clone() and bio_clone_kmalloc() as wrappers around it, making use of the functionality the last patch adedd. This will also help in a later patch changing how bio cloning works.
