Daniel Verkamp 71a6f0a790 sys_util: add write_zeroes_all() function ... In the same spirit as write_all() for the standard io::Write::write() function, add a write_zeroes_all() function with a default implementation that calls write_zeroes() in a loop until the requested length is met. This will allow write_zeroes implementations that don't necessarily fulfill the entire requested length. BUG=None TEST=cargo test -p sys_util write_zeroes Change-Id: I0fc3a4b3fe8904946e253ab8a2687555b12657be Signed-off-by: Daniel Verkamp <dverkamp@chromium.org> Reviewed-on: https://chromium-review.googlesource.com/c/chromiumos/platform/crosvm/+/1811466 Reviewed-by: Zach Reizner <zachr@chromium.org> Reviewed-by: Cody Schuffelen <schuffelen@google.com> Tested-by: kokoro <noreply+kokoro@google.com>		2019-09-25 00:06:27 +00:00
