Currently ld_read/write_done is called in default workqueue, which is not really a good place for IO path code. Trond mentioned that nfsiod is not an ideal place for it either. So do we need to create a pnfs private workqueue for this? Any other suggestions? -- Thanks, -Bergwolf -- To unsubscribe from this list: send the line "unsubscribe linux-nfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
