Hi Omar, Do you still have your AT_REPLACE patches? You said that you'd post a v4 series, though I don't see it. I could make use of such a feature in cachefiles inside the kernel. For my original question, see: https://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs.git/log/?h=fscache-iter And do you have ext4 support for it?
