This is a conversion to make the various file_operations structs in fs/ const. Basically a regexp job, with a few manual fixups The goal is both to increase correctness (harder to accidentally write to shared datastructures) and reducing the false sharing of cachelines with things that get dirty in .data (while .rodata is nicely read only and thus cache clean) Signed-off-by: NArjan van de Ven <arjan@infradead.org> Signed-off-by: NAndrew Morton <akpm@osdl.org> Signed-off-by: NLinus Torvalds <torvalds@osdl.org>

Now that get_block() can handle mapping multiple disk blocks, no need to have ->get_blocks(). This patch removes fs specific ->get_blocks() added for DIO and makes it users use get_block() instead.

This patch changes mpage_readpages() and get_block() to get the disk mapping information for multiple blocks at the same time. b_size represents the amount of disk mapping that needs to mapped. On the successful get_block() b_size indicates the amount of disk mapping thats actually mapped. Only the filesystems who care to use this information and provide multiple disk blocks at a time can choose to do so. No changes are needed for the filesystems who wants to ignore this.

Change the kmem_cache_create calls for certain slab caches to support cpuset memory spreading. See the previous patches, cpuset_mem_spread, for an explanation of cpuset memory spreading, and cpuset_mem_spread_slab_cache for the slab cache support for memory spreading. The slab caches marked for now are: dentry_cache, inode_cache, some xfs slab caches, and buffer_head. This list may change over time. In particular, other file system types that are used extensively on large NUMA systems may want to allow for spreading their directory and inode slab cache entries.

由 Andrew Morton 提交于
When we stop allocating percpu memory for not-possible CPUs we must not touch the percpu data for not-possible CPUs at all. The correct way of doing this is to test cpu_possible() or to use for_each_cpu(). This patch is a kernel-wide sweep of all instances of NR_CPUS. I found very few instances of this bug, if any. But the patch converts lots of open-coded test to use the preferred helper macros.

Extract central migration code from vmscan.c 3. Extract some components from mempolicy.c 4. Export pageout() and remove_from_swap() from vmscan.c 5. Make it possible to configure NUMA systems without page migration and non-NUMA systems with page migration. I had to so some #ifdeffing in mempolicy.c that may need a cleanup.

conversion and concurrent truncate operations. Use vn_iowait to wait for the completion of any pending DIOs. Since the truncate requires exclusive IOLOCK, so this blocks any further DIO operations since DIO write also needs exclusive IOBLOCK. This serves as a barrier and prevent any potential starvation.
