typos: fix similar typos to successfull
Mainline commit 73ac36ea14fd18ea3dc057e41b16ff31a3c0bd5a
When I review ocfs2 code, find there are 2 typos to "successfull". After
doing grep "successfull " in kernel tree, 22 typos found totally -- great
minds always think alike :)
This patch fixes all the similar typos. Thanks for Randy's ack and comments.

ocfs2/dlm: Fix race during lockres mastery
Mainline commit 7b791d68562e4ce5ab57cbacb10a1ad4ee33956e
dlm_get_lock_resource() is supposed to return a lock resource with a proper
master. If multiple concurrent threads attempt to lookup the lockres for the
same lockid while the lock mastery in underway, one or more threads are likely
to return a lockres without a proper master.
This patch makes the threads wait in dlm_get_lock_resource() while the mastery
is underway, ensuring all threads return the lockres with a proper master.
This issue is known to be limited to users using the flock() syscall. For all
other fs operations, the ocfs2 dlmglue layer serializes the dlm op for each
lockid.
Users encountering this bug will see flock() return EINVAL and dmesg have the
following error:
ERROR: Dlm error "DLM_BADARGS" while calling dlmlock on resource <LOCKID>: bad api args

ocfs2/dlm: Fix race in adding/removing lockres' to/from the tracking list
Mainline commit b0d4f817ba5de8adb875ace594554a96d7737710
This patch adds a new lock, dlm->tracking_lock, to protect adding/removing
lockres' to/from the dlm->tracking_list. We were previously using dlm->spinlock
for the same, but that proved inadequate as we could be freeing a lockres from
a context that did not hold that lock. As the new lock only protects this list,
we can explicitly take it when removing the lockres from the tracking list.
This bug was exposed when testing multiple processes concurrently flock() the
same file.

ocfs2/dlm: Hold off sending lockres drop ref message while lockres is migrating
Mainline commit d4f7e650e55af6b235871126f747da88600e8040
During lockres purge, o2dlm sends a drop reference message to the lockres
master. This patch delays the message if the lockres is being migrated.

ocfs2/dlm: Fix a race between migrate request and exit domain
Mainline commit 2b83256407687613e906bee93d98a25339128a4d
Patch address a racing migrate request message and an exit domain message.
Instead of blocking exit domains for the duration of the migrate, we ignore
failure to deliver that message. This is because an exiting domain should
not have any active locks and thus has no role to play in the migration.

ocfs2: return 0 in page_mkwrite to let VFS retry.
Mainline commit 4c1bbf1ba631d7db61ce3462349a3f5d14ae3009
In ocfs2_page_mkwrite, we return -EINVAL when we found the page mapping
isn't updated, and it will cause the user space program get SIGBUS and
exit. The reason is that during race writeable mmap, we will do
unmap_mapping_range in ocfs2_data_downconvert_worker. The good thing is
that if we reuturn 0 in page_mkwrite, VFS will retry fault and then
call page_mkwrite again, so it is safe to return 0 here.

ocfs2: Let inode be really deleted when ocfs2_mknod_locked() fails

We forgot to set i_nlink to 0 when returning due to error from ocfs2_mknod_locked()
and thus inode was not properly released via ocfs2_delete_inode() (e.g. claimed
space was not released). Fix it.
