UBI: initialize static volumes with vol->used_bytes (cbd8a9d2) · Commits · 戴 / test

I came across a problem which seems to be present since: commit UBI: set correct gluebi device size ubi_create_gluebi() leaves mtd->size = 0 for static volumes. So even existing static volumes are initialized with a size of 0. Signed-off-by:
