This patchset cleans up page cache handling by replacing open coded shifts and adds with inline function calls. The ultimate goal is to replace all uses of PAGE_CACHE_xxx in the kernel through the use of these functions. All the functions take a mapping parameter. The mapping parameter is required if we want to support large block sizes in filesystems and block devices. Patchset against 2.6.24-rc6-mm1. V2->V3: - Audit to check that uses of page->mapping are valid. Improve a couple of places. Make it clearer how the mappings are determined and handled (see the comments of each patch for detailed descriptions). - Use a consistent method to determine the mapping if a function already does determine the inode via page->mapping->host. V1->V2: - Review by Dave Chinner. Multiple improvements and fixes. - Review by Fengguand Wu with more improvements. -- - To unsubscribe from this list: send the line "unsubscribe linux-fsdevel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
