* xfs: Combine CIL insert and prepare passesDave Chinner2013-08-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Now that all the log item preparation and formatting is done under the CIL lock, we can get rid of the intermediate log vector chain used to track items to be inserted into the CIL. We can already find all the items to be committed from the transaction handle, so as long as we attach the log vectors to the item before we insert the items into the CIL, we don't need to create a log vector chain to pass around. This means we can move all the item insertion code into and optimise it into a pair of simple passes across all the items in the transaction. The first pass does the formatting and accounting, the second inserts them all into the CIL. We keep this two pass split so that we can separate the CIL insertion - which must be done under the CIL spinlock - from the formatting. We could insert each item into the CIL with a single pass, but that massively increases the number of times we have to grab the CIL spinlock. It is much more efficient (and hence scalable) to do a batch operation and insert all objects in a single lock grab.

* xfs: avoid CIL allocation during insertDave Chinner2013-08-13
| | | | | | | | | | | | | | | | | | | | Now that we have the size of the log vector that has been allocated, we can determine if we need to allocate a new log vector for formatting and insertion. We only need to allocate a new vector if it won't fit into the existing buffer. However, we need to hold the CIL context lock while we do this so that we can't race with a push draining the currently queued log vectors. It is safe to do this as long as we do GFP_NOFS allocation to avoid avoid memory allocation recursing into the filesystem. Hence we can safely overwrite the existing log vector on the CIL if it is large enough to hold all the dirty regions of the current item.

* xfs: Reduce allocations during CIL insertionDave Chinner2013-08-13
| | | | | | | | | | | | | | | | | Now that we have the size of the object before the formatting pass is called, we can allocation the log vector and it's buffer in a single allocation rather than two separate allocations. Store the size of the allocated buffer in the log vector so that we potentially avoid allocation for future modifications of the object. While touching this code, remove the IOP_FORMAT definition.

* xfs: return log item size in IOP_SIZEDave Chinner2013-08-13
| | | | | | | | | | | | | | | To begin optimising the CIL commit process, we need to have IOP_SIZE return both the number of vectors and the size of the data pointed to by the vectors. This enables us to calculate the size ofthe memory allocation needed before the formatting step and reduces the number of memory allocations per item by one. While there, kill the IOP_SIZE macro.

The biggest issue here is xfs_bmap_finish() - userspace has it's own definition of this function, and so we need to move it out of xfs_bmap.[ch]. This means several other files need to include xfs_bmap_util.h as well. It also introduces and interesting dance for the stack switching code in xfs_bmapi_allocate().
