BTW, will this two patch depend on the others in this patch series ?Yes. You'll need patches that affect TCP at least so that TCP supports MSG_SPLICE_PAGES, so 04-08 and perhaps 09. It's also on top of the patches that remove ITER_PIPE on my iov-extract branch, but I don't think that should affect you.Why I asked this is because I only could see these two ceph relevant patches currently.
Depends on how you defined 'relevant', I guess. Only two patches modify ceph directly, but there's a dependency: to make those work, TCP needs altering also. David
