RFE: delalloc helpers for ext4
Last modified: 2009-01-20 15:22:30 EST
Although I don't currently plan to ship delalloc-enabled ext4 in the RHEL5.3
tech preview, it would be nice to have the minimal vfs/mm helpers in place in
the RHEL5.3 kernel for testing & future updates.
So this bug requests the addition of those changes for that support.
It's a minimal patch - current version is at:
This request was evaluated by Red Hat Product Management for inclusion in a Red
Hat Enterprise Linux maintenance release. Product Management has requested
further review of this request by Red Hat Engineering, for potential
inclusion in a Red Hat Enterprise Linux Update release for currently deployed
products. This request is not yet committed for inclusion in an Update
Adding to ext4 tracker.
The patch is a bit bigger than the previous comment suggests, but it's not invasive. 5.3 may ship w/o delalloc support in ext4, but it would still be good, I think, to have the hooks in the kernel for further development and testing, and it would let us provide test ext4 kernel modules with delalloc, and still run on a stock RHEL5.3 kernel.
You can download this test kernel from http://people.redhat.com/dzickus/el5
