Part of this is definitely an e2fsck bug, because e2fsck isn't currently checking the EXT2_EXTENT_FLAGS_UNINIT flag. In line 1715 of e2fsck/pass1.c: start_block = pb->last_block = extent.e_lblk + extent.e_len - 1; We shouldn't be setting pb->last_block if this is an unitialized extent. I suspect this is also related though to the issue you raised in the "e2fsprogs and blocks outside i_size" thread about two weeks ago. So even after we fix this e2fsck bug, we may still have some fsstress failures until we decide how to deal with that particular issue. Do you have a quickie program that calls fallocate to preallocate space for a particular program easily to hand? If not, I can write one in about 5-10 minutes, but if you have one written already, it'll save me the effort.
