Any reason these implementations don't simply use vasprinf/asprintf? The calling conventions are a little differet, but the wrappers are pretty trivial, e.g.: http://git.infradead.org/?p=users/hch/xfsprogs.git;a=commitdiff;h=1f66530b2104b2f5e47aef76fce62df436a8f004 for asprintf. Also in general іt's nice to split such infrastruture additions into separate commits. The rest looks good: Reviewed-by: Christoph Hellwig <hch@xxxxxx>
