This series add a new file system I/O path that uses the iomap structure introduced for the pNFS support and support multi-page buffered writes. This was first started by Dave Chinner a long time ago, then I did beat it into shape for production runs in a very constrained ARM NAS enviroment for Tuxera almost as long ago, and now half a dozen rewrites later it's back. The basic idea is to avoid the crazy per-block get_blocks overhead and make use of extents in the buffered write path by iterating over them instead. Chances since V1: - add support for fiemap - fix a test fail on 1k block sizes - prepare for 64-bit length, this will be used in a follow on patchset -- 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
