Dave, may I ask you kindly for briefly elaborating on the worst consequences of just reverting this hunk, as I've done before? > > BTW, your patches do not apply to Linus' current git tree either: > > patching file fs/xfs/quota/xfs_qm.c > > Hunk #1 succeeded at 72 (offset 3 lines). > > Hunk #2 FAILED at 2120. > > 1 out of 2 hunks FAILED -- saving rejects to file > > fs/xfs/quota/xfs_qm.c.rej I'm able to resolve this, but 2.6.34-current > > does give me some other trouble, that I need to get by (PS2 keyboard > > stops working eventually).. > > Yeah, there's another patch in my xfs-dev tree that changes that. > I'll rebase it on a clean linux tree before I post it again. I've briefly tested this with a codebase somewhere between -rc3 and -rc4, and it survived the du test, but it suffered from some strange network drop outs, that aren't funny on a nfs server... Will retest your patches after opensuse-current catched up with -rc4. Hopefully, the most blatant stability issues are fixed by then.
