tools/liblockdep: Remove all build files when doing make clean

2014-05-08T17:55:13Z

We forgot to remove the shared library with the version number when 'make clean' ran, fix the clean pattern. Signed-off-by: Sasha Levin

perf tools: Remove extra '/' character in events file path

2014-04-30T15:02:24Z

The array debugfs_known_mountpoints[] will cause extra '/' character output. Remove it. pre: $ perf probe -l /sys/kernel/debug//tracing/uprobe_events file does not exist - please rebuild kernel with CONFIG_UPROBE_EVENTS. post: $ perf probe -l /sys/kernel/debug/tracing/uprobe_events file does not exist - please rebuild kernel with CONFIG_UPROBE_EVENTS.

tools lib traceevent: Fix memory leak in pretty_print()

2014-04-23T11:19:30Z

Commit 12e55569a244 "tools lib traceevent: Use helper trace-seq in print functions like kernel does" added a extra trace_seq helper to process string arguments like the kernel does it. But the difference between the kernel and the userspace library is that the kernel's trace_seq structure has a static allocated buffer. The userspace one has a dynamically allocated one. It requires a trace_seq_destroy(), otherwise it produces a nasty memory leak.

tools lib traceevent: Fix backward compatibility macros for pevent filter enums

2014-04-23T11:19:23Z

The return value for pevent_filter_match() is suppose to return FILTER_NONE if the event doesn't have a filter, and FILTER_NOEXIST if there is no filter at all. But the change 41e12e580a7 "tools lib traceevent: Refactor pevent_filter_match() to get rid of die()" replaced the return value with PEVENT_ERRNO__* values and added "backward compatibility" macros that used the old names. Unfortunately, the NOEXIST and NONE macros were swapped, and this broke users that use the old return names.

tools lib traceevent: Do not call warning() directly

2014-04-14T10:55:00Z

The patch 3a3ffa2e82205 ("tools lib traceevent: Report better error message on bad function args") added the error message but it seems there's no reason to call warning() directly. So change it to do_warning_event() to provide event information too.

tools lib traceevent: Print event name when show warning if possible

2014-04-14T10:55:00Z

It's sometimes useful to know where the parse failure was occurred. Add do_warning_event() macro to see the failing event. It now shows the messages like below: $ perf test 5 5: parse events tests : Warning: [kvmmmu:kvm_mmu_get_page] bad op token { Warning: [kvmmmu:kvm_mmu_sync_page] bad op token { Warning: [kvmmmu:kvm_mmu_unsync_page] bad op token { Warning: [kvmmmu:kvm_mmu_prepare_zap_page] bad op token { Warning: [kvmmmu:fast_page_fault] function is_writable_pte not defined Warning: [xen:xen_mmu_ptep_modify_prot_commit] function sizeof not defined Warning: [xen:xen_mmu_ptep_modify_prot_start] function sizeof not defined Warning: [xen:xen_mmu_set_pgd] function sizeof not defined Warning: [xen:xen_mmu_set_pud] function sizeof not defined Warning: [xen:xen_mmu_set_pmd] function sizeof not defined ...

tools/liblockdep: Add proper versioning to the shared obj

2014-04-01T15:46:10Z

Add proper versioning to the shared obj so that distros would be able to ship this lib without having to worry about versioning. Suggested-by: Josh Boyer Signed-off-by: Sasha Levin
