+Subject: Restore sendfile support
+
+Summary:
+Somehow in the kdelibs -> framework port the cmake checks for
+HAVE_SENDFILE got lost.
+
+That re-enables a massive optimisation in the file kioslave that has all the code existing and used in kdelibs4 that we're currently missing.
+
+Test Plan:
+Put a compilation fail inside the #ifdef, before it wasn't triggered, now it is.
+
+Ran unit tests
+Moved a file in dolphin

+Subject: Use correct variable type for returned value from read/sendfile
+
+Summary:
+n stores the read/transferred bytes. This returns a ssize_t.
+We were casting to an int, which theoretically is a loss of data.
+
+In practice it isn't an issue as we only read a max of MAX_IPC_SIZE at a
+time, which would fit in an int.
