Subject: Subpagesize-blocksize: Allow I/O on blocks whose size is less than page size
Date: Tue, 17 Sep 2019 10:31:04 +0200 [thread overview]
Message-ID: <5e481d4f4f323226a2c81caf5e2f78ae@linuxsystems.it> (raw)
Hi,
What happened to the subpagesize-blocksize patchset? It seems to be
untouched since 3 years.
I'm currently stuck on Fedora ppc64le because it ships with a 64k page
size, but I need it to be 4k in order to be able to chroot into foreign
architectures (like x86_64) with qemu-user.
If I try to mount my btrfs partition with a kernel with page size set to
4k I get the following error:
sectorsize 65536 not supported yet, only support 4094
I didn't try the patchset, because it doesn't support compression and my
whole fs is compressed.
It looked like an awesome work, why didn't it get merged?
Bests,
Niccolo'
