kernel 4.9 was added to longterm supported kernels https://lkml.org/lkml/2017/1/19/339
from https://man7.org/linux/man-pages/man2/readv.2.html > preadv2() and pwritev2() first appeared in Linux 4.6. Library support was added in glibc 2.26.
@ThomasWaldmann look like `RWF_UNCACHED` flag was introduced in [kenel 5.5 ](https://sjp38.github.io/post/lkml_news_v5.5-rc2/)
hmm... i check latest kernel source and do not find any string with `RWF_UNCACHED`. So look like this work unfinished yet.
Yet another work that can help speedup walk through files https://lwn.net/Articles/843163/
@ThomasWaldmann Sorry, I don't know how borg can use this. This is just for information, maybe someone can find how to use it in the future.
