Given the log a pointer to the AIL When we need to go from the log to the AIL, we have to go via the xfs_mount. Add a xfs_ail pointer to the log so we can go directly to the AIL associated with the log. Signed-off-by: Dave Chinner <david@fromorbit.com> Merge of xfs-linux-melb:xfs-kern:32351a by kenmcd.

Move memory allocations for log tracing out of the critical path Memory allocations for log->l_grant_trace and iclog->ic_trace are done on demand when the first event is logged. In xlog_state_get_iclog_space() we call xlog_trace_iclog() under a spinlock and allocating memory here can cause us to sleep with a spinlock held and deadlock the system. For the log grant tracing we use KM_NOSLEEP but that means we can lose trace entries. Since there is no locking to serialize the log grant tracing we could race and have multiple allocations and leak memory. So move the allocations to where we initialize the log/iclog structures. Use KM_NOFS to avoid recursing into the filesystem and drop log->l_trace since it's not even used. Merge of xfs-linux-melb:xfs-kern:31896a by kenmcd.

Convert l_flushsema to a sv_t The l_flushsema doesn't exactly have completion semantics, nor mutex semantics. It's used as a list of tasks which are waiting to be notified that a flush has completed. It was also being used in a way that was potentially racy, depending on the semaphore implementation. By using a sv_t instead of a semaphore we avoid the need for a separate counter, since we know we just need to wake everything on the queue. Original waitqueue implementation from Matthew Wilcox.

Reorganise xlog_t for better cacheline isolation of contention To reduce contention on the log in large CPU count, separate out different parts of the xlog_t structure onto different cachelines.

Remove the xlog_ticket allocator The ticket allocator is just a simple slab implementation internal to the log. It requires the icloglock to be held when manipulating it and this contributes to contention on that lock. Just kill the entire allocator and use a memory zone instead. While there, allow us to gracefully fail allocation with ENOMEM. Merge of xfs-linux-melb:xfs-kern:30771a by kenmcd. Remove the xlog_ticket allocator and replace it with a memory zone.

Per iclog callback chain lock Rather than use the icloglock for protecting the iclog completion callback chain, use a new per-iclog lock so that walking the callback chain doesn't require holding a global lock. This reduces contention on the icloglock during transaction commit and log I/O completion by reducing the number of times we need to hold the global icloglock during these operations.

Use atomics for iclog reference counting Now that we update the log tail LSN less frequently on transaction completion, we pass the contention straight to the global log state lock (l_iclog_lock) during transaction completion. We currently have to take this lock to decrement the iclog reference count. there is a reference count on each iclog, so we need to take þhe global lock for all refcount changes. When large numbers of processes are all doing small trnasctions, the iclog reference counts will be quite high, and the state change that absolutely requires the l_iclog_lock is the except rather than the norm. Change the reference counting on the iclogs to use atomic_inc/dec so that we can use atomic_dec_and_lock during transaction completion and avoid the need for grabbing the l_iclog_lock for every reference count decrement except the one that matters - the last. Merge of xfs-linux-melb:xfs-kern:30505a by kenmcd. change ic_refcount to an atomic_t.

clean up some xfs_log_priv.h macros - the various assign lsn macros are replaced by a single inline, xlog_assign_lsn, which is equivalent to ASSIGN_ANY_LSN_HOST except for a more sane calling convention. ASSIGN_LSN_DISK is replaced by xlog_assign_lsn and a manual bytespap, and ASSIGN_LSN by the same, except we pass the cycle and block arguments explicitly instead of a log paramter. The latter two variants only had 2, respectively one user anyway. - the GET_CYCLE is replaced by a xlog_get_cycle inline with exactly the same calling conventions. - GET_CLIENT_ID is replaced by xlog_get_client_id which leaves away the unused arch argument. Instead of conditional defintions depending on host endianess we now do an unconditional swap and shift then, which generates equal code. - the unused XLOG_SET macro is removed.

Add tail pointer to log structure. This way the ticket free list can be used in a circular fashion which makes debugging easier. This will not be used in non-debug mode since caching is affected.

1. Add another buffer to log, used for the case where a log record gets split in two when wrapping the physical log. 2. Put iclog into bp->b_fsprivate field. The original hack no longer works when a log record gets split in two. 3. Add lots of ASSERT statements 4. Re-use ic_refcnt field, so split writes will only kick off one iodone() for the pair of writes. 5. Add original reservation length field in ticket for correct accounting of reservations.

Revised state machine locking w.r.t. the counting semaphore used to hold off new log writers. There is now an ordering placed on in-core logs.

Add the notion of a start record for transactions. 4. Every 512 byte block will have a pass number stamped in the first word of the block. However, log record headers have their magic number in the first word with the pass number in the second word. 5. Add notion of splitting individual regions across multiple log record writes.

Most of the log state machine works now. The incore logs are now managed in a ring. As part of the state machine, the MP locks are in place for MP operation. More states have been added to the state machine. A test program can now write 2 log records and the commit record which requires reusing an iclog.
