Tom Rix 5e6ded2e7a livepatch: Reorder to use before freeing a pointer ... Clang static analysis reports this issue livepatch-shadow-fix1.c:113:2: warning: Use of memory after it is freed pr_info("%s: dummy @ %p, prevented leak @ %p\n", ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ The pointer is freed in the previous statement. Reorder the pr_info to report before the free. Similar issue in livepatch-shadow-fix2.c Note that it is a false positive. pr_info() just prints the address. The freed memory is not accessed. Well, the static analyzer could not know this easily.
