  . Introduce a layer/interface REISER4_TXMOD_PLUGIN_TYPE called at
    flush time to perform high-level block allocation in various
    contexts;
  . Add 2 TXMOD plugins (allocators):
    1) JOURNAL_TXMOD_ID, which implements classic Journalling
       transaction model;
    2) WA_TXMOD_ID, which implements classic Write-Anywhere (COW)
       transaction model;
  . Add the single hardcoded allocation introduced by Hans and Josh as
    a (default) HYBRID_TXMOD_ID plugin;
  . Add new mount options to specify the transaction models.

  management to FILE plugins in accordance with inode's
  plugin table (pset);
. Update comments.


Reiser4-for-3.6.4:

Edward Shishkin

Fixed bug in the flush procedure (squeeze_right_twig):
update dkeys of the pair of nodes, which took participation
in the "implicit shift" determined by the following pair of
functions:

. squalloc_extent()         - append units to the @left
. squalloc_right_twig_cut() - cut the units from @right


Reiser4-for-3.6.2:

Ivan Shapovalov

. i_dentry is now hlist;
. kill write_super of super_ops:

  sync_supers". It kills ->write_super() along with its sole
  user, thread sync_supers. Removed from reiser4.
. kunmap_atomic became single:
  upstream commit 167885e593 "feature-removal-schedule.txt:
  remove kmap_atomic(page, km_type)". The second argument was
  actually unused long ago. Kill it.

. create and lookup do not take nameidata

Edward Shishkin

. fixups in cryptcompress plugin:	
  Fix up the main search procedure of cryptcompress plugin:
  . make full-fledged tree traversal in the case when we
    encountered empty right neighbor;
  . unlock the left neighbor only in the case when we moved
    to right.
. lock the wb-list, when calling writeback_sb_inodes;
. Capture super block when syncing fs to synchronize the
  superblock with the other stuff. Make gcc happy.

. lock ->i_mutex in reiser4_sync_file_common();
. Introduce INODE_{INC,DROP,CLEAR,SET}_NLINK macros,
  which use library function for i_nlink manipulations;

  rcu-walk;
. Don't clear nlink in reiser4's do_create_vfs_child().
