ocfs2/net: Use wait_event() in o2net_send_message_vec()
Mainline commit 9af0b38ff3f4f79c62dd909405b113bf7c1a23aa
Replace wait_event_interruptible() with wait_event() in o2net_send_message_vec().
This is because this function is called by the dlm that expects signals to be
blocked.

ocfs2: fdatasync should skip unimportant metadata writeout
Mainline commit e04cc15f52eb072937cec2bbd8499f37afe5e1ef
In ocfs2, fdatasync and fsync are identical.
I think fdatasync should skip committing transaction when
inode->i_state is set just I_DIRTY_SYNC and this indicates
only atime or/and mtime updates.
Following patch improves fdatasync throughput.

ocfs2: Timer to queue scan of all orphan
Mainline commit bd1fda0725338a1a831cf763c2cacccd83d2776e
When a dentry is unlinked, the unlinking node takes an EX on the dentry lock
before moving the dentry to the orphan directory. Other nodes that have
this dentry in cache have a PR on the same dentry lock. When the EX is
requested, the other nodes flag the corresponding inode as MAYBE_ORPHANED
during downconvert. The inode is finally deleted when the last node to iput
the inode sees that i_nlink==0 and the MAYBE_ORPHANED flag is set.
A problem arises if a node is forced to free dentry locks because of memory
pressure. If this happens, the node will no longer get downconvert
notifications for the dentries that have been unlinked on another node.
If it also happens that node is actively using the corresponding inode and
happens to be the one performing the last iput on that inode, it will fail
to delete the inode as it will not have the MAYBE_ORPHANED flag set.
This patch fixes this shortcoming by introducing a periodic scan of the
orphan directories to delete such inodes. Care has been taken to distribute
the workload across the cluster so that no one node has to perform the task
all the time.

ocfs2: Correct ordering of ip_alloc_sem and localloc locks for directories
Mainline commit edd45c08499a3e9d4c25431cd2b6a9ce5f692c92
We use ordering ip_alloc_sem -> local alloc locks in ocfs2_write_begin().
So change lock ordering in ocfs2_extend_dir() and ocfs2_expand_inline_dir()
to also use this lock ordering.

ocfs2: Use nd_set_link()
Mainline commit a731d12d6ddd1e703770cacb5dfecb155b03ee06
ocfs2 was hand-calling vfs_follow_link(), but there's no point to that.
Let's use page_follow_link_light() and nd_set_link().

ocfs2: update comments in masklog.h
Mainline commit 2b53bc7bff17341d8b5ac12115f5c2363638e628
In the mainline ocfs2 code, the interface for masklog is in files under
/sys/fs/o2cb/masklog, but the comments in fs/ocfs2/cluster/masklog.h
reference the old /proc interface. They are out of date.
This patch modifies the comments in cluster/masklog.h, which also provides
a bash script example on how to change the log mask bits.
