    perf trace augmented_syscalls: Augment bind's 'myaddr' sockaddr arg · 02ef2884
    Arnaldo Carvalho de Melo authored
    One more, to reuse the augmented_sockaddr_syscall_enter() macro
    introduced from the augmentation of connect's sockaddr arg, also to get
    a subset of the struct arg augmentations done using the manual method,
    before switching to something automatic, using tracefs's format file or,
    even better, BTF containing the syscall args structs.
