    Btrfs: use the commit_root for reading free_space_inode crcs · 2cf8572d
    Chris Mason authored
    Now that we are using regular file crcs for the free space cache,
    we can deadlock if we try to read the free_space_inode while we are
    updating the crc tree.
    
    This commit fixes things by using the commit_root to read the crcs.  This is
    safe because we the free space cache file would already be loaded if
    that block group had been changed in the current transaction.
