To improbe usability, support %[PROVIDER:]SDTEVENT format to
add new probes on SDT and cached events.
e.g.
# perf probe -x /lib/libc-2.17.so %lll_lock_wait_private
Added new event:
sdt_libc:lll_lock_wait_private (on %lll_lock_wait_private in
/usr/lib/libc
Support @BUILDID or @FILE suffix for SDT events. This allows
perf to add probes on SDTs/pre-cached events on given FILE
or the file which has given BUILDID (also, this complements
BUILDID.)
For example, both gcc and libstdc++ has same SDTs as below.
If you would like to add a probe on sdt_libstdcxx
Fix to show correct error messages for $vars and $params because
those special variables requires debug information to find the
real variables or function parameters.
E.g. without this fix;
# perf probe -x /lib64/libc-2.23.so getaddrinfo \$params
Failed to write event: Invalid argument
Allo glob wildcard for reusing cached/SDT events. E.g.
# perf probe -x /usr/lib64/libc-2.20.so -a %sdt_libc:\*
This example adds probes for all SDT in libc.
Note that the SDTs must have been scanned by perf buildid-cache.

Hi,
Here is the 14th version of the patchset for probe-cache and
initial SDT support.

Search SDT/cached event from all probe caches if user doesn't

Support a special SDT probe format which can omit the '%' prefix
only if the SDT group name starts with "sdt_". So, for example
both of "%sdt_libc:setjump" and "sdt_libc:setjump" are acceptable
for perf probe --add.
E.g. without this:

This checks whether sys/sdt.h is available or not,
which is required for DTRACE_PROBE().
We can disable this feature by passing NO_SDT=1 when
building.
This flag will be used for SDT test case and further
SDT events in perftools.

The VM_BUG_ON_PAGE in page_move_anon_rmap() is more trouble than it's
worth: the syzkaller fuzzer hit it again. It's still wrong for some
THP cases, because linear_page_index() was never intended to apply to
addresses before the start of a vma.
That's easily fixed with a signed long cast inside l

selfcompiled 4.7-rc6 and 4.7-rc7 sometimes crash with NMI from
