New Revision: 240011
URL: http://svn.freebsd.org/changeset/base/240011

Log:
  Partially revert r239959, after actually fixing most of the clang
  warnings in sys/gnu/fs/xfs.  The only warnings that still need to be
  suppressed are those about array bound overruns of flexible array
  members in xfs_dir2_{block,sf}.c, which are too expensive (in terms of
  cascading code changes) to fix.
  
  MFC after:	1 week
  X-MFC-With:	r239959
