* This file defines a few internal symbols that all start with "LSS_".
* Do not access these symbols from outside this file. They are not part
* of the supported API.
- *
- * NOTE: This is a stripped down version of the official opensource
- * version of linux_syscall_support.h, which lives at
- * http://code.google.com/p/linux-syscall-support/
- * It includes only the syscalls that are used in perftools, plus a
- * few extra. Here's the breakdown:
- * 1) Perftools uses these: grep -rho 'sys_[a-z0-9_A-Z]* *(' src | sort -u
- * sys__exit(
- * sys_clone(
- * sys_close(
- * sys_fcntl(
- * sys_fstat(
- * sys_futex(
- * sys_futex1(
- * sys_getcpu(
- * sys_getdents(
- * sys_getppid(
- * sys_gettid(
- * sys_lseek(
- * sys_mmap(
- * sys_mremap(
- * sys_munmap(
- * sys_open(
- * sys_pipe(
- * sys_prctl(
- * sys_ptrace(
- * sys_ptrace_detach(
- * sys_read(
- * sys_sched_yield(
- * sys_sigaction(
- * sys_sigaltstack(
- * sys_sigdelset(
- * sys_sigfillset(
- * sys_sigprocmask(
- * sys_socket(
- * sys_stat(
- * sys_waitpid(
- * 2) These are used as subroutines of the above:
- * sys_getpid -- gettid
- * sys_kill -- ptrace_detach
- * sys_restore -- sigaction
- * sys_restore_rt -- sigaction
- * sys_socketcall -- socket
- * sys_wait4 -- waitpid
- * 3) I left these in even though they're not used. They either
- * complement the above (write vs read) or are variants (rt_sigaction):
- * sys_fstat64
- * sys_getdents64
- * sys_llseek
- * sys_mmap2
- * sys_openat
- * sys_rt_sigaction
- * sys_rt_sigprocmask
- * sys_sigaddset
- * sys_sigemptyset
- * sys_stat64
- * sys_write
