f2fs: Export the enums in the tracepoints to userspace (5511b9a4) · Commits · 戴 / test

The tracepoints that use __print_symbolic() use enums as the value to convert to strings. Unfortunately, the format files for these tracepoints show the enum name and not their value. This causes some userspace tools not to know how to convert __print_symbolic() to their strings. Add TRACE_DEFINE_ENUM() macros to export the enums used to userspace to let those tools know what those enum values are.
