+Subject: [PATCH] staging: vcsm-cma: Fixup the alloc code handling of
+ kernel_id
+
+The allocation code had been copied in from an old branch prior
+to having added the IDR for 64bit support. It was therefore pushing
+a pointer into the kernel_id field instead of an IDR handle, the
+lookup therefore failed, and we never released the buffer.
