    Btrfs: Add mount -o compress-force · a555f810
    Chris Mason 提交于
    The default btrfs mount -o compress mode will quickly back off
    compressing a file if it notices that compression does not reduce the
    size of the data being written.  This can save considerable CPU because
    all future writes to the file go through uncompressed.
    
    But some files are both very large and have mixed data stored in
    them.  In that case, we want to add the ability to always try
    compressing data before writing it.
    
    This commit adds mount -o compress-force.  A later commit will add
    a new inode flag that does the same thing.
