And a heads up that I had to rebase this branch today, something I haven't done during the .31 cycle. This was due to the history being really odd, with modified patches of for-2.6.32 patches being forwarded to mainline. So I though it would be better to clean this history and merge fixups. There was also a middle point that would break bisection. Nothing really earth shattering in here, nor are there really big changes for this cycle. - Some updates to CFQ to improve interactiveness. - Some cleanups and sanitization of the bio IO flags. - blk-iopoll, an experimental API for doing NAPI like polled completions for really fast devices. In testing this has shown to be faster for some cases, while slower for others. The included patch is just the core bits, no driver support is being merged yet. - Enable CPU IO completion by default. My testing has shown this to be faster, and independent testing by Intel confirms that as well. - A fix to only issue a block queue trace when we actually intend to queue. - A fix for splice to update mtime and atime on files. - A cleanup of the failfast bits and merge fixups for the same. The changes are availble at: git://git.kernel.dk/linux-2.6-block.git for-2.6.32 Ed L.
