The only exception is ll_update_inode where dropping != NULL

6c9e5a55cb staging: lustre: DLC Feature dynamic net config
This is the third patch of a set of patches that enables DLC.

This patch adds the following features to LNET.  Currently these
features are not driven by user space.
- Adding/Deleting Networks dynamically
Two new functions were added:
 - lnet_dyn_add_ni()
    add an NI. if the NI is already added then fail with
    appropriate error code
 - lnet_dyn_del_ni()
    delete an existing NI.  If NI doesn't exist fail with
    appropriate failure code.
These functions shall be called from IOCTL.

86ef6250fc staging: lustre: Dynamic LNet Configuration (DLC) dynamic routing
This is the second patch of a set of patches that enables DLC.

This patch adds the following features to LNET.  Currently these
features are not driven by user space.
- Enabling Routing on Demand.  The default number of router
  buffers are allocated.
- Disable Routing on demand. Unused router buffers are freed and
  used router buffers are freed when they are no longer in use.
  The following time routing is enabled the default router buffer
  values are used.  It has been decided that remembering the
  user set router buffer values should be remembered and re-set
  by user space scripts.
- Increase the number of router buffers on demand, by allocating
  new ones.
- Decrease the number of router buffers.  Exccess buffers are freed
  if they are not in use.  Otherwise they are freed once they are
  no longer in use.

ec5fb5be77 staging: lustre: return +ve for blocked lnet message
returned value of lnet_post_send_locked and
lnet_post_routed_recv_locked are changed to -ve by:
http://review.whamcloud.com/#/c/9369/

this is wrong because callers rely on +ve to identify blocked
message which is not a failure.

To respect linux kernel coding style and not use positive error
code, this patch adds two macros as non-error returned values of
these functions:
    LNET_CREDIT_OK    has credit for message
    LNET_CREDIT_WAIT  no credit and message is blocked

both these functions will return these two values instead of 0
and EAGAIN

060c2820d0 staging: lustre: remove uses of IS_ERR_VALUE()
Remove most uses of IS_ERR_VALUE(). This macro was often given an int
argument coming from PTR_ERR(). This invokes implementation defined
behavior since the long value gotten by applying PTR_ERR() to a kernel
pointer will usually not be representable as an int. Moreover it may
be just plain wrong to do this since the expressions IS_ERR(p) and
IS_ERR_VALUE((int) PTR_ERR(p)) are not equivalent for a general
pointer p.

fe747f0f34 staging: wilc1000: Return correct error codes
This change has been made with the goal that kernel functions should
return something more descriptive than -1 on failure.

The return value on an alloc_etherdev failure should be -ENOMEM,
and not -1.

This was found using Coccinelle. A simplified version of the semantic
patch used is:

//<smpl>
@@
expression *e;
identifier l1;
@@

e = alloc_etherdev(...);
if (e == NULL) {
...
return
- -1
+ -ENOMEM
;
}
//</smpl

Furthermore, introduced `ret` variable to store and return the
corresponding error code returned by register_netdev on failure.

The two call sites store the return value in a variable which only
checks that the value is non-zero, hence no change is required at
the call sites.

changes return type to void and removes a brace of if statement due to
have a single statement.

b713ce0e49 staging: wilc1000: handle_set_mac_address: remove debug message of kmalloc failure
There is no need to print debug message when kmalloc is failed. This
message is redundant. The code already show us that kmalloc is failed.
The brace of if statement is remove as well due to have a single
statement.

so this cleans up the remains.
