remove noops when stderr isn't present; just fail instead.

- cleanups in sanity-gns.sh
- added one more GNS test - mounting directory with absent mount object

- more fixes in GNS stuff:
  - fixes with refcount onto @dchild in ll_gns_mount_object() for error control paths
  - fixing using accessing @dchild in the case of IS_ERR(dchild)

  - disabled checking for GNS file in mds_open(), thus GNS mount points are also
    opening by now. This is needed, because in taking lock we can't reliable to detect
    GNS objects on MDS. Checking just suid bit and skip open such a dirs is not correct
    as one may create structure like dir/dir/dir and mark all of them by suid.

  - cleanups in sanity-gns.sh. Added few new tests for odd conditions like mount object
    is symlink, dir, etc. Added test for changing mount object name to "." and "..".
    Grouping tests into 2 groups:

    (1) general GNS tests - mounting/umounting on timeout with different conditions
    with possible deadlocks, races, etc.

    (2) checking for odd conditions like recursive suid bit marked mount points, etc

  - small optimization in ll_gns_wait_for_mount(), changing return code semantics to
    usual 0 - ok, < 0 error.

  - handled possible nested mount with returning -ERETSARTSYS and causing endless loop
    of mounting.

  - check if found mount object is regular file to prevent from evil cases like it is
    suid bit marked directory, etc.

  - fix with completting all waiters for dentry mounting in progress.
  - added check for "." and ".." names in setting gns_object_name.
  - fixed default gns_object_name value.

  - removed ll_d_lookup() as it is not used anymore.

  - removed struts from real_lookup() with calling revalidate() after lookup if dentry
    is marked GNS_MOUNTING. By now all this dentry marking is not needed anymore.

  - ll_gns_mount_object() is now called from ll_revalidate_it() and ll_lookup_it()

  - fixed deadlock when one thread T1 waits for mount completion and another one T2
    created by upcall script waits for dentry->d_inode->i_sem. By now -ERESTARTSYS
    is returned for T2 and others and whren they restart syscall, dentry is mounted
    already or some error occured and GNS state is READY for mount.

  - fixes in comments and header of llite_gns.c

  - fixed possible incorrect spin_unlock() in ll_gns_mount_object()

  - using lookup_one_len() for looking for mount object instead of d_lookup() which
    looks only in dcache.

  - fixed handling of negative mount object dentry in ll_gns_mount_object()

  - fixed readding mount object content. By now kernel_read() is used instead of
    readpage approach.

  - waking up all possible waiters on finishing GNS mount. Nevertheless in current
    stuff nobody seem waits for mount (-RESTARTSYS is used instead), completion
    exists and it is semanticaly correct to wake up all its waiters. In fact this
    is needed for possible future using. If it happen that nobody will wait on it
    and it is counted not needed, it will be removed.

be called in interrupt context.

MDS_BACKFSTYPE and OST_BACKFSTYPE are defined for this.
FSTYPE is ldiskfs for 2.6 kernel by default

- small fix about check_type() function

-replace CERROR with CDEBUG()
-check strings before using.

remove untested stuff. Additional testing is needed at first.

r=wangdi

changes for smfs support:
1. realdev in prepare() is set to device name, not to 'smfs'. This fixes bug 6143.
2. backdev is not used, instead of it real device name used for --dev parameter in smfs configuration.

update kml and lru stuff in accordance with new DLD for SMFS
remove unused file journal.c
add changes to Makefile
using new options retrival method in smfs_lib

r=alex

changes related to iopen support, fc3 compatibility and new smfs plugin API

replace several 'if' that check non-allowed situations with LASSERT()

adding sets of smfs fsfilt methods
adds some new HOOKs

move smfs methods to smfs dir.

r=alex
d=24-33

support for iopen
FC3 compatibility

r=alex
d=24-33

support for iopen and cmd in smfs methods.

r=alex
d=26-33

support for iopen/cmd/wantedi for smfs

Handle "./lustrecvs -r foo" instead of choking.

r=<awaiting from eeb>

 - use correspondent list anchor

add 2.6.10 fc3 kernel config

accessing not initialized MDCs in the case of errors.

1)minor fix and cleanup dev_rd_only kernel patch on HEAD
2)add sec support on kernel config
3)some cleanup

add signal bug fix  to uml patch

- removed hardcoded checking for ".mntinfo" on MDS to see if we are trying to open GNS mount object. By now only suid bit on directory is checked. This should not break anything, as it is not used for any purpose.

- cleanups, moving not needed to be widely known llite functions to llite_internal.h

- added test_4a to sanity-gns.sh. It checks how GNS mounting works with 20 concurrent threads aiming to mount the same object.

minor fix in lkcd patch

some patches fix for lustre in FC3
