+Subject: [PATCH] mksquashfs: fix regression introduced by SEEK_DATA
+ optimisation
+
+The representation of a sparse block was changed from 0 to a negative
+number.  This was to optimise sparse buffer passing between threads, and
+where a single buffer can now represent a multi-block sparse span.
+
+Unfortunately some code was not correctly updated, and this was not
+picked up in testing.
+
+Fixes: https://github.com/plougher/squashfs-tools/issues/336
