Fixing the following scenario: - A request is on the waiters list waiting for a reply from a remote node. - The request is the first one on the resource, so first_lkid is set. - The remote node fails causing recovery. - During recovery the requesting node becomes master. - The request is now processed locally instead of being a remote operation. - At this point we need to call confirm_master() on the resource since we're certain we're now the master node. This will clear first_lkid. - We weren't calling confirm_master(), so first_lkid was not being cleared causing subsequent requests on that resource to get stuck.

This splits the rwlocks guarding the hash chains of the glock hash table into their own array. This will reduce memory usage in some cases due to better alignment, although the real reason for doing it is to allow the two tables to be different sizes in future (i.e. the locks will be sized proportionally with the max number of CPUs and the hash chains sized proportinally with the size of physical memory) In order to allow this, the gl_bucket member of struct gfs2_glock has now become gl_hash, so we record the hash rather than a pointer to the bucket itself.

As requested by Jan Engelhardt, this removes the typedefs in the locking module interface and replaces them with void *. Also since we are changing the interface, I've added a few consts as well.

This code is no longer used for anything and can be removed from the locking modules. The sync_lvb function is not required as this happens automatically with the current locking system. Signed-off-by: NSteven Whitehouse <swhiteho@redhat.com>

This removes one of the typedefs from the locking interface. It is replaced by a forward declaration of the gfs2 superblock. The other two are not so easy to solve since in their case, they can refer to one of two possible structures.

There are several reasons why we want to do this: - Firstly its large and thus we'll scale better with multiple GFS2 fs mounted at the same time - Secondly its easier to scale its size as required (thats a plan for later patches) - Thirdly, we can use kzalloc rather than vmalloc when allocating the superblock (its now only 4888 bytes) - Fourth its all part of my plan to eventually be able to use RCU with the glock hash.
