In the case of event->type, gcc could compile the switch statement into a jump table, effectively ending up reading the type field multiple times. This is part of XSA-155. Signed-off-by: Stefano Stabellini commit 74fab2ef4c0ba42af477e9e445c9883cc45cf9e6 Author: Stefano Stabellini Date: Fri Dec 18 15:44:58 2015 +0000 xen/blkif: Avoid double access to src->nr_segments src is stored in shared memory and src->nr_segments is dereferenced twice at the end of the function. If a compiler decides to compile this into two separate memory accesses then the size limitation could be bypassed. Fix it by removing the double access to src->nr_segments. This is part of XSA-155.
