    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: 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.
