We've been steadily reducing the number of places which rely on PG_error. There are only two left, so the first five patches remove those dependencies. Every patch after the jfs patch is independent, and can be taken by the respective maintainer immediately. They might depend on patches I sent in the last week or two (eg jfs, ntfs3). Obviously I've done no testing beyond compilation. All patches can be found on linux-fsdevel. I've bcc'd this cover letter to all the maintainers, and cc'd each patch to whoever's listed in the MAINTAINERS file.
