Hello!

   It seems our first attempt of sending these to Linus have failed,
   here is another one.

Bye,
    Oleg

    reiserfs updates:

    These first two changesets contain fixes for reiserfs. They fix issue with
    handling of displacing_large_files allocator option and a problem with
    remounting from readwrite to readwrite mode if FS holds some deleted but
    not yet closed files.

    Next three changesets implement reiserfs_file_write. Also third one
    exports generic_osync_inode,block_commit_write and remove_suid
    because these are now needed for reiserfs.
    There was no reiserfs_file_write in the 2.4 port of reiserfs
    (and Hans was very unhappy about it).
    With current 'one block at a time' algorithm, writes past the end of a file
    are slow because each new file block is separately added into the tree
    causing shifting of other items which is CPU expensive.
    With this new implementation if you write into file with big enough chunks,
    it uses half as much CPU. Also this version is more SMP friendly than
    the current one.

    Next four changesets replace recently added lock_kernels with
    reiserfs wrappers (that would eventually evolve into real separate
    locks), includes more C99 designated initialisers cleanups (this time
    from Art Haas) and updates some reiserfs help entries. Also fixing a
    buglet in reiserfs_file_write code discovered during some 2.4.20-pre
    testing.
