Vendors have included hooks for this in 2.4 already anyway. So on technical grounds, I'm strongly inclined to support it, but I would like to suggest that it is ensured that the hook is sufficient for all of the named CFS. Paul, have you spoken with them? > b) Does the IBM filsystem meet the kernel's licensing requirements? If you are worried about this one, you can export it GPL-only, which as an Open Source developer I'd appreciate, but from a real-world business perspective would be unhappy about ;-) Sincerely, Lars Marowsky-Bree -- High Availability & Clustering \ ever tried. ever failed. no matter.
