* ocfs2: Remove struct ocfs2_journal_handle in favor of handle_tMark Fasheh2006-12-011-75/+20
| | | | | | | | | | This is mostly a search and replace as ocfs2_journal_handle is now no more than a container for a handle_t pointer. ocfs2_commit_trans() becomes very straight forward, and we remove some out of date comments / code. Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>
* ocfs2: remove handle argument to ocfs2_start_trans()Mark Fasheh2006-12-011-21/+8
| | | | | | | | | All callers either pass in NULL directly, or a local variable that is already set to NULL. The internals of ocfs2_start_trans() get a nice cleanup as a result. Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>
* ocfs2: remove ocfs2_journal_handle journal fieldMark Fasheh2006-12-011-2/+0
| | | | | | It is no longer used. Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>
* ocfs2: pass ocfs2_super * into ocfs2_commit_trans()Mark Fasheh2006-12-011-2/+3
| | | | | | This sets us up to remove handle->journal. Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>
* ocfs2: remove unused handle argument from ocfs2_meta_lock_full()Mark Fasheh2006-12-011-6/+4
| | | | | | Now that this is unused and all callers pass NULL, we can safely remove it. Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>
* ocfs2: make ocfs2_alloc_handle() staticMark Fasheh2006-12-011-1/+1
| | | | | | This is no longer used outside of journal.c Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>
* ocfs2: remove unused ocfs2_handle_add_lock()Mark Fasheh2006-12-011-78/+2
| | | | | | | | | | This gets us rid of a slab we no longer need, as well as removing the majority of what's left on ocfs2_journal_handle. ocfs2_commit_unstarted_handle() has no more real work to do, so remove that function too. Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>
* ocfs2: remove unused ocfs2_handle_add_inode()Mark Fasheh2006-12-011-43/+0
| | | | | | | | We can also delete the unused infrastructure which was once in place to support this functionality. ocfs2_inode_private loses ip_handle and ip_handle_list. ocfs2_journal_handle loses handle_list. Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>
* ocfs2: remove ocfs2_journal_handle flags fieldMark Fasheh2006-12-011-12/+1
| | | | | | | | Callers can set h_sync directly on the handle_t, whether a transaction has been started or not can be determined via the existence of the handle_t on the struct ocfs2_journal_handle. Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>
* ocfs2: have ocfs2_extend_trans() take handle_tMark Fasheh2006-12-011-6/+3
| | | | | | | | | | No reason to use our wrapper struct in this function, so take the handle_t directly. Also fixes a bug where we were incorrectly setting the handle to NULL in case of a failure from journal_restart() Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>
* ocfs2: remove unused ocfs2_journal_handle fieldMark Fasheh2006-12-011-6/+1

* ocfs2: Remove i_generation from inode lock namesMark Fasheh2006-09-241-1/+2
| | | | | | | | | | | | | | | | | | | | | | | 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>
* ocfs2: clean up some osb fieldsMark Fasheh2006-06-291-3/+2
| | | | | | | | Get rid of osb->uuid, osb->proc_sub_dir, and osb->osb_id. Those fields were unused, or could easily be removed. As a result, we also no longer need MAX_OSB_ID or ocfs2_globals_lock. Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>
* [PATCH] spin/rwlock init cleanupsIngo Molnar2006-06-271-1/+1
| | | | | | | | | | | | | | | | | | | | | 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>

* [PATCH] change buffer_head.b_size to size_tBadari Pulavarty2006-03-261-1/+1
| | | | | | | | | | | | | | Increase the size of the buffer_head b_size field (only) for 64 bit platforms. Update some old and moldy comments in and around the structure as well. The b_size increase allows us to perform larger mappings and allocations for large I/O requests from userspace, which tie in with other changes allowing the get_block_t() interface to map multiple blocks at once.

* [PATCH] ocfs2: fix orphan recovery deadlockMark Fasheh2006-03-011-31/+93
| | | | | | | | | Orphan dir recovery can deadlock with another process in ocfs2_delete_inode() in some corner cases. Fix this by tracking recovery state more closely and allowing it to handle inode wipes which might deadlock. Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>
* [PATCH] ocfs2: only checkpoint journal when asked toMark Fasheh2006-02-161-4/+3
| | | | | | | | Disable automatic checkpointing of the journal - this is a relic from older ocfs2 days. Worth quite a bit of performance on longer running single node tests. Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>
* [PATCH] ocfs2: don't wait on recovery when locking journalMark Fasheh2006-02-031-1/+5
| | | | | | | | The mount path had incorrectly asked the locking code to wait for recovery completion, which deadlocks things because recovery waits for mount to complete first. Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>
