RFI -- GFS patches into 2.4 kernel
Last modified: 2007-04-18 12:30:36 EDT
Would like to see the GFS Patches included in the main kernel so that GFS
is an easy add-on.

From the GFS kernel patches README:
Patches to the Linux Kernel 2.4
These patches are against 2.4.0-prerelease
[These are the essential ones to get GFS working under 2.4.xx kernels]
bufcache.patch - Adds callbacks to buffer cache for GFS. Once GFS has
migrated to using the page cache entirely, this will
not be required.
ksyms.patch - Exports symbols required by GFS. This patch contains the
GFS specific changes that will be required to the kernel.
From time to time this patch will be submitted to the
main kernel tree, so if bits of it don't apply to your
kernel source, it may be because its made its way into
the main tree already.
task.patch - Adds a hook to the task_struct to hang the GFS transaction
inode.patch - Adds an extra argument to read_inode() to handle the 64bit
inode numbers cleanly. N.B. This isn't the "right" way to
do this, so this will change.
[These are not uptodate compared with the latest kernel version and may not
still be required/working]
exportscsi.patch - exports "rscsi_disks" symbol for Dlock.
cdb16.patch - A version of cdb16.patch for 2.3.xx kernels

The old patches, exportscsi.patch and cdb16.patch, are out of date and need
to be redone when we port Pool to 2.4. (But they aren't needed if you're
not doing Pool.)
Bufcache.patch, ksyms.patch, and inode.patch are close, but both need a
bit more work.
task.patch is pretty close to its final form.
nfs.patch is just a bug fix. It has been submitted and will hopefully be

task.patch and bufcache.patch will both probably go in (or an equivelant
will go in) when Stephen Tweedie get ext3 into the kernel.
inode.patch needs to be synced up with what Al Viro wants to do with the
new iget4() interface.
ksyms.patch doesn't really do anything controversial, so we may submit that

Sistina Software, Inc.
GFS is now non-free software. The chances of us doing this therefor
went from "good when the code quality improves sufficiently" to
"no chance whatsoever, sorry".
I see Alan and Arjan are active on the lists.
GFS is not in a state where it is supportable. Sistina GFS 4.1 has dozens and
dozens of serious (some exploitable) bugs, OpenGFS is cleaning this up a lot
now, but lack of equipment slows it down a bit.
