05973c2efb orangefs: Dan Carpenter influenced cleanups...
This patch is simlar to one Dan Carpenter sent me, cleans
up some return codes and whitespace errors. There was one
place where he thought inserting an error message into
the ring buffer might be too chatty, I hope I convinced him
othewise. As a consolation <g> I changed a truly chatty
error message in another location into a debug message,
system-admins had already yelled at me about that one...

9a19a6db37 Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs
Pull vfs updates from Al Viro:

 - more ->d_init() stuff (work.dcache)

 - pathname resolution cleanups (work.namei)

 - a few missing iov_iter primitives - copy_from_iter_full() and
   friends. Either copy the full requested amount, advance the iterator
   and return true, or fail, return false and do _not_ advance the
   iterator. Quite a few open-coded callers converted (and became more
   readable and harder to fuck up that way) (work.iov_iter)

 - several assorted patches, the big one being logfs removal

* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs:
  logfs: remove from tree
  vfs: fix put_compat_statfs64() does not handle errors
  namei: fold should_follow_link() with the step into not-followed link
  namei: pass both WALK_GET and WALK_MORE to should_follow_link()
  namei: invert WALK_PUT logics
  namei: shift interpretation of LOOKUP_FOLLOW inside should_follow_link()
  namei: saner calling conventions for mountpoint_last()
  namei.c: get rid of user_path_parent()
  switch getfrag callbacks to ..._full() primitives
  make skb_add_data,{_nocache}() and skb_copy_to_page_nocache() advance only on success
  [iov_iter] new primitives - copy_from_iter_full() and friends
  don't open-code file_inode()
  ceph: switch to use of ->d_init()
  ceph: unify dentry_operations instances
  lustre: switch to use of ->d_init()

4defb5f912 orangefs: fix memory leak of string 'new' on exit path
allocates string 'new' is not free'd on the exit path when
cdm_element_count <= 0. Fix this by kfree'ing it.

Fixes CoverityScan CID#1375923 "Resource Leak"

19ff7fcc76 orangefs: add .owner to debugfs file_operations
Without ".owner = THIS_MODULE" it is possible to crash the kernel
by unloading the Orangefs module while someone is reading debugfs
files.

dc0336214e orangefs: clean up debugfs
We recently refactored the Orangefs debugfs code.
The refactor seemed to trigger dan.carpenter@oracle.com's
static tester to find a possible double-free in the code.

While designing the fix we saw a condition under which the
buffer being freed could also be overflowed.

We also realized how to rebuild the related debugfs file's
"contents" (a string) without deleting and re-creating the file.

This fix should eliminate the possible double-free, the
potential overflow and improve code readability.

44f4641073 orangefs: clean up debugfs globals
Mostly this is moving code into orangefs-debugfs.c so that globals turn
into static globals.

Then gossip_debug_mask is renamed orangefs_gossip_debug_mask but keeps
global visibility, so it can be used from a macro.

2fa37fd713 Orangefs: fix ifnullfree.cocci warnings
fs/orangefs/orangefs-debugfs.c:130:2-26: WARNING: NULL check before freeing functions like kfree, debugfs_remove, debugfs_remove_recursive or usb_free_urb is not needed. Maybe consider reorganizing relevant code to avoid passing NULL values.

 NULL check before some freeing functions is not needed.

 Based on checkpatch warning
 "kfree(NULL) is safe this check is probably not required"
 and kfreeaddr.cocci by Julia Lawall.
