[PATCH 0/3] tool lib traceevent: Fix some parsing errors

From: Steven Rostedt
Date: Tue Mar 24 2020 - 16:10:06 EST



Arnaldo,

Here's a few patches for lib traceevent.

The first one adds an "append()" helper function for appending to strings,
which will also simplify the next patch.

The second patch handles "__attribute__((user))" in the field of a
trace event. This is needed after the stack leak code added this
to parameters of system call events.

The last patch adds handling of __builtin_expect(), as someone wanted
to move IS_ERR_VALUE() from the fast path into the print fmt section,
which breaks the parsing. This should also be useful for other macros
that may evaluate down to a __builtin_expect().

Steven Rostedt (VMware) (3):
tools lib traceevent: Add append() function helper for appending strings
tools lib traceevent: Handle __attribute__((user)) in field names
tools lib traceevent: Add handler for __builtin_expect()
