[Bug 1322976] Re: [precise] dosfsck is unable to repair FS

[Pali]

I updated description.

** Description changed:

+ [Impact]
+ 
  dosfsck is unable to repair FS and kernel show this warning:
  
  FAT-fs (sdc1): Volume was not properly unmounted. Some data may be
  corrupt. Please run fsck.
  
  This problem happends when 3.8+ kernel does not properly umount fat
  partion. For fixing this problem dosfstools v3.0.14+ is needed. See:
  https://lkml.org/lkml/2013/5/6/342
  
  Because in precise is only version 3.0.12-1ubuntu1.1, it cannot repair
  these FS. So please update in precise dosfsck to at least version
  v3.0.14 which can properly fix fat32 partitions.

+ 
+ [Test Case]
+ 
+ Mount some FAT partition in R/W mode and stop/crash kernel. Next time
+ run fsck on that partition and dosfsck should properly clean dirty bit.
+ Kernel should not show message "Volume was not properly unmounted".
+ 
+ [Regression Potential]

+ Low/None. Mentioned patch which fix this problem is already included in
+ upstream dosfstools version.
