* [patch 3/3] OCFS2 Configurable timeouts - Protocol changesAndrew Beekhof2006-12-114-16/+116
| | | | | | | | | | | | | | | | | | | | | | Modify the OCFS2 handshake to ensure essential timeouts are configured identically on all nodes. Only allow changes when there are no connected peers Improves the logic in o2net_advance_rx() which broke now that sizeof(struct o2net_handshake) is greater than sizeof(struct o2net_msg) Included is the field for userspace-heartbeat timeout to avoid the need for further protocol changes. Uses a global spinlock to ensure the decisions to update configfs entries are made on the correct value. The region covered by the spinlock when incrementing the counter is much larger as this is the more critical case.

* ocfs2: Remove i_generation from inode lock namesMark Fasheh2006-09-241-1/+4
| | | | | | | | | | | | | | | | | | | | | | | OCFS2 puts inode meta data in the "lock value block" provided by the DLM. Typically, i_generation is encoded in the lock name so that a deleted inode on and a new one in the same block don't share the same lvb. Unfortunately, that scheme means that the read in ocfs2_read_locked_inode() is potentially thrown away as soon as the meta data lock is taken - we cannot encode the lock name without first knowing i_generation, which requires a disk read. This patch encodes i_generation in the inode meta data lvb, and removes the value from the inode meta data lock name. This way, the read can be covered by a lock, and at the same time we can distinguish between an up to date and a stale LVB. This will help cold-cache stat(2) performance in particular. Since this patch changes the protocol version, we take the opportunity to do a minor re-organization of two of the LVB fields. Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>

* [PATCH] spin/rwlock init cleanupsIngo Molnar2006-06-272-2/+2
| | | | | | | | | | | | | | | | | | | | | locking init cleanups: - convert " = SPIN_LOCK_UNLOCKED" to spin_lock_init() or DEFINE_SPINLOCK() - convert rwlocks in a similar manner this patch was generated automatically. Motivation: - cleanliness - lockdep needs control of lock initialization, which the open-coded variants do not give - it's also useful for -rt and for lock debugging in general Signed-off-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Arjan van de Ven <arjan@linux.intel.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

| | | | | | | | | | | | | | The check to determine which format string is appopriate for u64 and friends works in most cases, but UML on x86_64 doesn't define CONFIG_X86_64, so it results in screen fulls of compile-time warnings.
