I've just posted an assembly of all of the outstanding raw IO bugfixes I know of, to ftp.uk.linux.org:/pub/linux/sct/fs/raw-io and ftp.*.kernel.org:/pub/linux/kernel/people/sct/raw-io in kiobuf-2.2.18pre24.tar.gz. README is appended below. Eric, this contains at least one bug fix that was missing from your patch set --- we need a flush_dcache_page() after obtaining the mapping on some CPUs (spotted by davem). I've kept the bigmem and non-bigmem versions separate. Your CONFIG_BIGMEM code did some rather weird (though not strictly buggy) things in the case of a non-bigmem-enabled kernel. Linus and co are doing a set of cleanups for 2.4 dirty page handling, and I'll redo all of the fixes here for 2.4 once that is in place. The really important bugfix is the fault-handling one, and we can't do that reliably without the VM changes in place.
