svn commit: r218485 - in head/sys/ufs: ffs ufs

[Alexander Leidinger]

Author: netchild
Date: Wed Feb  9 15:33:13 2011
New Revision: 218485
URL: http://svn.freebsd.org/changeset/base/218485

Log:
  Add some FEATURE macros for some UFS features.
  
  SU+J is not included as a FEATURE macro:
   - it was not in the tree during the GSoC
   - I do not see an option to en-/disable it in NOTES
  
  Two minor changes where made during the review compared to what was developed
  during GSoC 2010.
  
  No FreeBSD version bump, the userland application to query the features will
  be committed last and can serve as an indication of the availablility if
  needed.
