New Revision: 183754
URL: http://svn.freebsd.org/changeset/base/183754

Log:
  Remove the struct thread unuseful argument from bufobj interface.
  In particular following functions KPI results modified:
  - bufobj_invalbuf()
  - bufsync()
  
  and BO_SYNC() "virtual method" of the buffer objects set.
  Main consumers of bufobj functions are affected by this change too and,
  in particular, functions which changed their KPI are:
  - vinvalbuf()
  - g_vfs_close()
  
  Due to the KPI breakage, __FreeBSD_version will be bumped in a later
  commit.
  
  As a side note, please consider just temporary the 'curthread' argument
  passing to VOP_SYNC() (in bufsync()) as it will be axed out ASAP
