2009-12-30tracing: Fix sign fields in ftrace_define_fields_##call()Lai Jiangshan
Add is_signed_type() call to trace_define_field() in ftrace macros. The code previously just passed in 0 (false), disregarding whether or not the field was actually a signed type. Signed-off-by: Lai Jiangshan <laijs@cn.fujitsu.com> LKML-Reference: <4B273D3A.6020007@cn.fujitsu.com> Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
2009-12-30tracing/syscalls: Fix typo in SYSCALL_DEFINE0Lai Jiangshan
The struct syscall_metadata variable name in SYSCALL_DEFINE0 should be __syscall_meta__##sname instead of __syscall_meta_##sname to match the name that is in SYSCALL_DEFINE1/2/3/4/5/6. This error causes event_enter_##sname->data to point to the wrong location, which causes syscalls which are defined by SYSCALL_DEFINE0() not to be traced.

2009-12-30tracing/kprobe: Show sign of fields in trace_kprobe format filesLai Jiangshan
The format files of trace_kprobe do not show the sign of the fields. The other format files show the field signed type of the fields and this patch makes the trace_kprobe formats consistent with the others.

2009-12-30ksym_tracer: Remove trace_statLi Zefan
trace_stat is problematic. Don't use it, use seqfile instead. This fixes a race that reading the stat file is not protected by any lock, which can lead to use after free.

2009-12-21tracing: Fix setting tracer specific optionsSteven Rostedt
The function __set_tracer_option() takes as its last parameter a "neg" value. If set it should negate the value of the option. The trace_options_write() passed the value written to the file which is what the new value needs to be set as. But since this is not the negative, it never sets the value.

Use a generic trace_event_raw_init() function for all event's raw_init callbacks (but kprobes) instead of defining the same version for each of these.

2009-12-12[BKL] add 'might_sleep()' to the outermost lock takerLinus Torvalds
As shown by the previous patch (6698e3472: "tty: Fix BKL taken under a spinlock bug introduced in the BKL split") the BKL removal is prone to some subtle issues, where removing the BKL in one place may in fact make a previously nested BKL call the new outer call, and then prone to nasty deadlocks with other spinlocks. In general, we should never take the BKL while we're holding a spinlock, so let's just add a "might_sleep()" to it (even though the BKL doesn't technically sleep - at least not yet), and we'll get nice warnings the next time this kind of problem happens during BKL removal.

2009-12-12tty: Fix BKL taken under a spinlock bug introduced in the BKL splitAlan Cox
The fasync path takes the BKL (it probably doesn't need to in fact) while holding the file_list spinlock. You can't do that with the kernel lock: it causes lock inversions and deadlocks.
