The most important change is to split the unrelated nommu mmap flags from it, but it also remove a backing_dev_info pointer from the address_space (and thus the inode) and cleans up various other minor bits. The remaining patches sort out the issues around bdi_unlink and now let the bdi life until it's embedding structure is freed, which must be equal or longer than the superblock using the bdi for writeback, and thus gets rid of the whole mess around reassining inodes to new bdis. -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
