speaking of fuse_dev_splice……_write actually, this series has broken xdg-document-portal! https://github.com/flatpak/xdg-desktop-portal/issues/2026 Specifically what happens is that the EINVAL is returned due to oh.len != nbytes: fuse_dev_do_write: oh.len 16400 != nbytes 15526 (where 16400 == 16384 (read len) + 16, 15526 == 15510 (file len) + 16) After reverting the series, there is no error because oh.len becomes 15526 too.
Please, test v2 version of my fixes: https://lore.kernel.org/lkml/20260625083409.3769242-1-safinaskar@gmail.com/ (local) . This should fix this bug. -- Askar Safin
