Good question actually. I know XFS does passed vmalloc'ed memory down the block I/O path, but that's as a scatter/gather request. All non-s/g request should be contingous I think.
We really need to write down the rules about what memory can be passed down the block I/O path - XFS for example sends kmalloced memory down which all the iSCSI implementations don't like at all. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
