Re: [Libguestfs] [PATCH v3 0/4] file: Zero for block devices and older file systems

FYI I added a few enhancements to allow easier tracing inside the file plugin: https://github.com/libguestfs/nbdkit/commit/10d4dcfb30cb0ba626a2ec503c7c9... https://github.com/libguestfs/nbdkit/commit/96a41cd798ec0dce07d97c2a4a04e... I learned from this that the file_zero function does successfully use fallocate to zero ranges, at least on my very recent Linux system.
