dlm: fix address compare

2008-09-02T19:32:08+00:00

Compare only the addr and port fields of sockaddr structures.
Fixes a problem with ipv6 where sin6_scope_id does not match.

dlm: rename structs

2008-08-13T17:47:36+00:00

Add a dlm_ prefix to the struct names in config.c.  This resolves a
conflict with struct node in particular, when include/linux/node.h
happens to be included.

configfs: Allow ->make_item() and ->make_group() to return detailed errors.

2008-07-17T22:21:29+00:00

The configfs operations ->make_item() and ->make_group() currently
return a new item/group.  A return of NULL signifies an error.  Because
of this, -ENOMEM is the only return code bubbled up the stack.

Multiple folks have requested the ability to return specific error codes
when these operations fail.  This patch adds that ability by changing the
->make_item/group() ops to return ERR_PTR() values.  These errors are
bubbled up appropriately.  NULL returns are changed to -ENOMEM for
compatibility.

Also updated are the in-kernel users of configfs.

This is a rework of reverted commit 11c3b79218390a139f2d474ee1e983a672d5839a.

dlm: recover nodes that are removed and re-added

2008-04-21T16:18:01+00:00

If a node is removed from a lockspace, and then added back before the
dlm is notified of the removal, the dlm will not detect the removal
and won't clear the old state from the node.  This is fixed by using a
list of added nodes so the membership recovery can detect when a newly
added node is already in the member list.

dlm: match signedness between dlm_config_info and cluster_set

2008-04-21T16:18:01+00:00

cluster_set is only called from the macro CLUSTER_ATTR which defines read/write
access functions.  Make the signedness match to avoid sparse warnings every time
CLUSTER_ATTR is used (lines 149-159) all of the form:

fs/dlm/config.c:149:1: warning: incorrect type in argument 3 (different signedness)
fs/dlm/config.c:149:1:    expected unsigned int *info_field

configfs: Convert subsystem semaphore to mutex

2007-07-11T00:10:56+00:00

Convert the su_sem member of struct configfs_subsystem to a struct
mutex, as that's what it is. Also convert all the users and update
Documentation/configfs.txt and Documentation/configfs_example.c
accordingly.
