UBIFS: remove incorrect index space check (8aabb750) · Commits · 戴 / test

When we report free space to user-space, we should not report 0 if the amount of empty LEBs is too low, because they would be produced by GC when needed. Thus, just call 'ubifs_calc_available()' straight away which would take 'min_idx_lebs' into account anyway. Signed-off-by:
