Hi. This is the second version of the complete series with the goal to remove ->bmap interface completely, in lieu of FIEMAP. This new version has been heavily modified in comparison with the first one, based on comments of Christoph and Andreas. And has been simplified. My apologies if I forgot to update anything based on previous discussion. Patch 1-3 has no difference from the previous version, and Christoph's Reviewed-by has been kept. Patch 4 is a V2 of the previous set, with updates required by Christoph (a local sector_t variable, and moving the patch earlier in the series. Patches 5-9 are essentially the modification of ->fiemap and deprecation of ->bmap. In this new version, I kept the current fiemap_extent_info structure, and moved into it all the required data for use in both FIEMAP and FIBMAP, instead of creating a new data structure as in the old patch set. This way, basically no heavy modification is required on individual filesystems, but the update of its fiemap methods, removing start and len arguments, once they will be passed now into fiemap_extent_info. Last patch, is the removal of ->bmap method into XFS, I decided to not add the previous patch for Ext4 because it needs more ext4 internal knowledge, which I don't have. Comments are much appreciated. Cheers P.S. I thought about merging patch 7 into patch 8, and, patch 6 into patch 5, but I decided to leave it as-is by now, and get comments about the way it is, and if people agree, I'll merge them.
