* Add the .call modifier to syscall entry probes.Przemyslaw Pawelczyk2009-10-121-349/+349
| | | | | | | | | | | | | | | | | | | | Inline functions do not have an indentifiable return point and require kernel built using VTA-enabled gcc to get tracking of variables. OTOH syscall functions are very rarely inlined (depending on the compiler mood), therefore filtering probes to include only non-inlined functions ensures consistent behavior between different kernels. This removes the problem of inaccessible variables in inlined syscalls that is described in comments #6-9 to PR5890 and gives us the status quo w.r.t. syscall probing, because before the commit solving PR10572 (b7478964) inline instances were masked anyway by non-inline ones. You can check whether you have inlined syscalls using following command: $ stap -l 'kernel.function("sys_*"),kernel.function("compat_sys_*")' \ 2>&1 -vvv | awk '/^selected inline/{print $5}' * tapset/syscalls.stp: Add .call to all entry probes. * tapset/syscalls2.stp: Ditto.
* Move the "pure" tag into the body of __is_user_regsJosh Stone2009-05-221-1/+2
| | | | | | The "/* pure */" tag has no effect unless it is within the embedded-C body of a function. In this instance, they were accidentally moved out during the syscall cleanups.
* Fix alignment of probe aliases in syscalls(|2).stp.Przemyslaw Pawelczyk2009-05-191-381/+381
| | | | | | | Align probe points in probe aliases to equal sign using spaces as it's already done in nd_syscalls.stp. Signed-off-by: Josh Stone <jistone@redhat.com>
* Unify formatting of syscalls.stp and syscalls2.stp.Przemyslaw Pawelczyk2009-05-191-500/+653
| | | | | | | | | | | | | | | Rules: - Specify probe points for aliases starting from the alias declaration line and with one probe point per line. - Use K&R indent style -- probe alias/point/function opening brace goes to the line following the declaration, other opening braces are kept on the same line as the control statements. - Indent using tabs. - Surround operators with spaces. - Put spaces after commas. - Avoid trailing whitespaces.
