LU-1978 llite: Fix i_size race with truncate and mkwrite

These changes address a race between the truncate
process and the mkwrite process. We add an additional
check in the case of a mkwrite to make sure we are not

The kernel will then return a SIGBUS. These changes
return -ENODATA to ensure we correctly clean up. In the
case of the mapping being null nothing will change.

LU-1606 api: Do not include lustre_idl.h from lustreapi.h

lustre_idl.h has become increasingly difficult to use from
user-space.  Normal users of the lustre api should not
be looking into lustre wire protocol anyway, so this change
eliminates the include of lustre_idl.h.

After removing lustre_idl.h, it became obvious that a number
of programs have been picking up normal user-space headers
through a very windy path of includes.  With the include
of lustre_idl.h gone, they no longer compiled, so we also
add the missing explicit includes.

It became clear that copytool.c explicity requires
libcfs/libcfs.h, and lustre_rsync.c require lustre_idl.h.
But I believe that it is far better to have those includes
explicitly stated, so it is obvious that those programs
are peeking into lustre's internals.  In the future we
can work on creating new lustre API calls that provide the
information that they need without side-stepping abstraction
layers.

LU-1623 mdt: Atomically update MDT export connection flags

MDT processing of connect requests currently updates the export
connection flags in two steps: client/server feature matching is
performed first, then much later various security-related bits are
removed as needed.  Certain error paths may leave the export flags
partially initialized.

A problem arises if multiple connect requests from the same client are
handled out of order, as may occur due to network disruptions. If the
last such request to be handled has a lower connection count than one
that already completed, it will be aborted with -EALREADY after having
modified the connection flags in the export.  However, the
security-related flags are left with incorrect values, as the
top-level connect handler skips setting these in the error path.
Replies to subsequent client requests may then contain unexpected
security information, causing the client to crash.

Similar issues may exist with other target types having non-atomic
export flag updates, and these should be addressed in follow-up
patches.

This patch makes the following changes:

- To avoid the problem described above, update the export connection
  flags atomically, and only in the successful case.

- To make this important atomic operation more conspicuous, move it
  from mdt_init_sec_level() to the top-level handler mdt_connect().

- Add a comment to mdt_connect_internal(), and delete a disabled code
  block from it.

- Correct debug message in target_handle_connect() to match code.

LU-1113 llite: hide DCACHE_LUSTRE_INVALID in ll_dentry_data

DCACHE_LUSTRE_INVALID is lustre private flag in vfs layer.
Replace it with dentry->d_fsdata->lld_invalid so that it won't
conflict with VFS flags.

After dcache scalability patch, dentry->d_fsdata is always set
before dentry is materised/rehashed. So if a dentry's d_fsdata
is not set, then it is not hashed/materised. The patch make use

necessary because d_lustre_invalidate() can be called in
ll_invalidate_negative_children() and finds unmaterised/unhashed
dentries.

Also drop all vfs_races patches as they are no longer needed.

LU-1714 lnet: Properly initialize sg_magic value

When the CONFIG_DEBUG_SG flag is enabled in the kernel, we must ensure
the sg_magic field is properly initialized. Otherwise, internal kernel
assertions will fail when trying to verify this field. As a result,
certain calls to sg_* function had to be changed or inserted to ensure
the sg_init_table function would be called, initializing the magic
value. Also, we need to ensure this value isn't zeroed out in the
