            I can propose it. We're technically past our feature request deadline, but I can present it as a late change request.

            Jeff since SLES11SP4 is not out just yet would you consider having the BH_LRU_SIZE and quota improvements merged into your kernel?

            Hi James, I'm afraid we're too late to incorporate the quota changes. SLE12 GA was released last week. The quota changes would change the kABI so we can't accept them into the release. Unless LU-3406 has changes substantially since I asked Neil Brown to take a look at it last year, we won't be able to accept that one either. He had serious reservations about whether it would end up causing corruption in use. The configurable BH_LRU_SIZE change might be acceptable since it's local to fs/buffer.c

            Jeff I like to discuss how to go about to make a pathless server for SLES12 support. Currently three primary patches are needed:

            bh_lru_size_config.patch - a simple which might change based on what will go upstream. Andrew Morton discuss just having BH_LRU_SIZE
            changes to 16 in the kernel.

            quota enhancement patches - These have already been merged upstream as the following commits

            commit b9ba6f94b2382ef832f97122976b73004f714714
            commit 9eb6463f31cf720deaf0e810cacc403d7720b10c
            commit 1ea06bec78a128adc995ca32bd906a6c9bb9cf91
            commit 606cdcca04a609ed4dfbfe788942de9477da556b
            commit d68aab6b8f572406aa93b45ef6483934dd3b54a6

            It would be really nice to have those merged into your tree.

            Lastly the work under LU-3406. That is just starting to get underway and once we have a proper solution then it could also be integrated as well.
