98 Objtool's stack validation feature analyzes every .o file and ensures
99 the validity of its stack metadata. It enforces a set of rules on asm
100 code and C inline assembly code so that stack traces can be reliable.
111 Here are some of the benefits of validating stack metadata:
113 a) More reliable stack traces for frame pointer enabled kernels
116 code and debug tools to be able to walk the stack to determine the
