    hfsplus: fix expand when not enough available space · 059a704c
    Sergei Antonov 提交于
    Fix a bug which is reproduced as follows. Create a file:
    
     echo abc > test_file
    
    Try to expand the file beyond available space:
    
     truncate --size=<size exceeding available space> test_file
    
    Since HFS+ does not support file size > allocated size, truncate should
    fail.  However, it ends successfully.  The driver returns success despite
    having been unable to allocate the requested space for the file.  Also
    filesystem check finds an error:
    
     Checking catalog file.
     Incorrect size for file test_file
     (It should be 469094400 instead of 1000000000)
    
    Add a piece of code analogous to code in the fat driver.  Now a proper
    error is returned and filesystem remains consistent.
