perf trace: Use the ptr->name beautifier as default for "filename" args

2016-05-23T19:41:00Z

Auto-attach the ptr->name beautifier to syscall args "filename", "path" and "pathname" if they are of type "const char *".

perf trace: Use the fd->name beautifier as default for "fd" args

2016-05-23T19:41:00Z

Noticed when the 'setsockopt' 'fd' arg wasn't being formatted via the SCA_FD beautifier, so just remove the setting of "fd" args to SCA_FD and do it when reading the syscall info, like we do for args of type "pid_t", i.e. "fd" as the name should be enough as the decision to use the SFA_FD beautifier. For odd cases we can just do it explicitely.

perf trace: Only auto set call-graph to "dwarf" when syscalls are being traced

2016-05-20T14:43:57Z

When --min-stack or --max-stack is passwd but --no-syscalls is also in effect, there is no point in automatically setting '--call-graph dwarf'.

perf tools: Fix usage of max_stack sysctl

2016-05-20T14:43:56Z

We cannot limit processing stacks from the current value of the sysctl, as we may be processing perf.data files, possibly from other machines. Instead use the old PERF_MAX_STACK_DEPTH, the sysctl default, that can be overriden using --max-stack or equivalent.

perf trace: Fix exit_group() formatting

2016-05-20T14:43:55Z

This doesn't return, so there is no raw_syscalls:sys_exit for it, add the ending ')', without any return value, since it is void.

perf trace: Warn when trying to resolve kernel addresses with kptr_restrict=1

2016-05-20T14:43:54Z

Hook into the libtraceevent plugin kernel symbol resolver to warn the user that that can't happen with kptr_restrict=1.
