Uncached Buffered I/O Aims To Be Ready For Linux 6.14 With Big Gains

[hwertz]

RWF_UNCACHED gives you the benefit of the kernel doing writeback, like it normally does with cached I/O, but the blocks just won't stick around in the cache once they're no longer dirty.

All the better, given the massive speed benefit that can be had just by combining a few smaller writes into a larger one and all that.

IO_uring improvements work or not for end-users?
