The k-way merge used by srch file compaction only dropped the second entry in a pair of duplicate entries. Duplicate entries are both supposed to be removed so that entries for removed xattrs don't take up space in the files. This both drops the second entry and removes the first encoded entry. As we encode entries we rememeber their starting offset and the previous entry that they were encoded from. When we hit a duplicate entry we undo the encoding of the previous entry. This only works wihin srch file blocks. We can still have duplicate entries that span blocks but that's unlikely and relatively harmless. Signed-off-by: Zach Brown <zab@versity.com>
