pwritev2? I have patches to support per-I/O O_DSYNC with it, lots of folks including Samba and SCSI targets want this because their protocols support it. The patches were posted with earlier versions of Miklos series. It's cleaner to add the two system calls in go when we plan using them anyway and have symmetric infrastructure, and I did not hear any disagreement with that on LSF.

We had everyone agree and nod there, and only your repeated argument here, so maybe it's not Miklos who is disonnected but you? Also that whole fincore argument is rather hypothetic - it's only been pushed in to ugly to live multiplexers that also expose things like pfns, while with preadv2 we have a trivial and easy to use API read to merge, and various consumerms just waiting for it. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
