Sometimes other drivers depend on particular configfs items. For example,
ocfs2 mounts depend on a heartbeat region item. If that region item is
removed with rmdir(2), the ocfs2 mount must BUG or go readonly. Not happy.
This provides two additional API calls: configfs_depend_item() and
configfs
Many folks know that I've been pretty stubborn on the subject of
configfs item removal. configfs_rmdir() cannot currently be aborted by
a client driver. This is to ensure that userspace has control - if
userspace wants to remove an item, it should have that ability. The
client driver is
ocfs2 mounts require a heartbeat region. Use the new configfs_depend_item()
facility to actually depend on them so they can't go away from under us.
First, teach cluster/nodemanager.c to depend an item on the o2cb subsystem.
Then teach o2hb_register_callbacks to take a UUID and depend on the
appr
