genetlink: only pass array to genl_register_family_with_ops()

2013-11-19T21:39:05Z

As suggested by David Miller, make genl_register_family_with_ops() a macro and pass only the array, evaluating ARRAY_SIZE() in the macro, this is a little safer. The openvswitch has some indirection, assing ops/n_ops directly in that code. This might ultimately just assign the pointers in the family initializations, saving the struct genl_family_and_ops and code (once mcast groups are handled differently.)

dlm: Avoid that dlm_release_lockspace() incorrectly returns -EBUSY

2013-10-16T15:32:42Z

When dlm_release_lockspace(ls, 1) is invoked on a busy system immediately after the last dlm_unlock() AST has finished it can occur that lkb_idr_is_local() is invoked for the unlocked LKB since removal from ls_lkbidr only occurs after the AST has returned. If that happens dlm_release_lockspace(ls, 1) will return -EBUSY instead of releasing the lockspace. Fix this race condition by changing lkb_idr_is_local() such that it only returns true for LKB's that have not yet been unlocked. Signed-off-by: Bart Van Assche Signed-off-by: David Teigland

dlm: remove signal blocking

The signal blocking was incorrect and unnecessary so just remove it. Signed-off-by: David Teigland

dlm: WQ_NON_REENTRANT is meaningless and going away

2013-07-30T14:24:24Z

dbf2576e37 ("workqueue: make all workqueues non-reentrant") made WQ_NON_REENTRANT no-op and the flag is going away. Remove its usages. This patch doesn't introduce any behavior changes. Signed-off-by: Tejun Heo Signed-off-by: David Teigland

dlm: Avoid LVB truncation

2013-06-26T16:38:02Z

For lockspaces with an LVB length above 64 bytes, avoid truncating the LVB while exchanging it with another node in the cluster. Signed-off-by: Bart Van Assche Signed-off-by: David Teigland

dlm: disable nagle for SCTP

2013-06-14T18:07:11Z

For TCP we disable Nagle and I cannot think of why it would be needed for SCTP. When disabled it seems to improve dlm_lock operations like it does for TCP. Signed-off-by: Mike Christie Signed-off-by: David Teigland

dlm: retry failed SCTP sends

2013-06-14T18:07:11Z

Currently if a SCTP send fails, we lose the data we were trying to send because the writequeue_entry is released when we do the send. When this happens other nodes will then hang waiting for a reply. This adds support for SCTP to retry the send operation. I also removed the retry limit for SCTP use, because we want to make sure we try every path during init time and for longer failures we want to continually retry in case paths come back up while trying other paths. We will do this until userspace tells us to stop. Signed-off-by: Mike Christie Signed-off-by: David Teigland
