SPARSE_MEMORY_PRESEN(9) 				    Memory Management in Linux					   SPARSE_MEMORY_PRESEN(9)

NAME

       sparse_memory_present_with_active_regions - Call memory_present for each active range

SYNOPSIS

       void sparse_memory_present_with_active_regions(int nid);

ARGUMENTS

       nid
	   The node to call memory_present for. If MAX_NUMNODES, all nodes will be used.

DESCRIPTION

       If an architecture guarantees that all ranges registered with add_active_ranges contain no holes and may be freed, this function may be
       used instead of calling memory_present manually.

NAME

       votequorum_qdevice_master_wins - Sets or clears quorum device master_wins flag

SYNOPSIS

       #include <corosync/votequorum.h>

       int votequorum_qdevice_master_wins(votequorum_handle_t handle const char name, unsigned int allow);

DESCRIPTION

       The votequorum_qdevice_master_wins informs votequorum whether or not the currently registered qdevice subsystem supports 'master_wins' mode
       (default 0).  This mode allows the qdevice to effectively take over the quorum calculations of votequorum. Any node with an active  qdevice
       that  also  has	master_wins set becomes quorate regardless of the node votes of the cluster. It is left up to the qdevice subsystem itself
       (not part of votequorum) to communicate across the nodes or otherwise provide some system of deciding which nodes will be part of the  quo-
       rate cluster, if any. eg They may be the set of nodes that has access to a quorum disk.
       name The name of the currently registered quorum device on this node. This must match the existing name known to votequorum.
       allow 0 (the default) means that master_wins is not active on this node. 1 means that master_wins is active on this node.

RETURN VALUE

       This call returns the CS_OK value if successful, otherwise an error is returned.
