syscalls for now, until we deal with 32-bit compat * Fix syscall exit * Fix sys exit * Only enable detailed syscalls for x86_64 for now * Merge unknown syscall method with extended detail method * Add underscore prefix before event names * Add syscalls pointers detailed syscall tracing * Use perl for regexp * Support generation of syscall probes for those with pointers * Support detailed syscalls with 0 arguments * detailed syscall tracing (work in progress) * Expose /proc/lttng file * Implement detailed syscall event probe * Disable perf build for < 2.6.33 kernels * Syscall detail mode: generate syscall table * block instrumentation: write cmd as hex sequence * lttng-events TRACE_EVENT generator cleanup * block layer instrumentation: fix cmd field * Remove 0 args syscalls for now from type-aware syscall cb generator * Generate trace syscall table macros * Put syscall tracing without arg types back in place * Detailed system call tracing (TRACE_EVENT() generation for integer support) * lttng events probes: don't clash with "ctx" variable name * lib ring buffer must take private pointer copy before decrementing refcount 2011-08-16 LTTng modules 2.0-pre8 * Fix metadata buffer wait/wakeup 2011-08-12 LTTng modules 2.0-pre7 * Add missing module refcount to lttng_tracepoint_list_fops * Add license info about lib/ringbuffer/ring_buffer_mmap.c being GPLv2
