Hello, I've noticed that in several places we need to unmap metadata in buffer cache for a range of blocks and we do it by iterating over all blocks in given range. Let's provide a helper function for that and implement it in a way more efficient for larger ranges of blocks. Also cleanup other uses of unmap_unerlying_metadata(). The patches passed xfstests for ext2 and ext4. Jens, can you merge these patches if they look fine to you? Changes since v1: * Improved comment describing what the function does * Renamed function * Added wrapper for single block users and use it Honza -- 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
