    Btrfs: Fix leaf reference cache miss · 5b84e8d6
    Yan Zheng 提交于
    Due to the optimization for truncate, tree leaves only containing
    checksum items can be deleted without being COW'ed first. This causes
    reference cache misses. The way to fix the miss is create cache
    entries for tree leaves only contain checksum.
    
    This patch also fixes a -EEXIST issue in shared reference cache.
