Steven Rostedt 553552ce17 tracing: Combine event filter_active and enable into single flags field ... The filter_active and enable both use an int (4 bytes each) to set a single flag. We can save 4 bytes per event by combining the two into a single integer. text data bss dec hex filename 4913961 1088356 861512 6863829 68bbd5 vmlinux.orig 4894944 1018052 861512 6774508 675eec vmlinux.id 4894871 1012292 861512 6768675 674823 vmlinux.flags This gives us another 5K in savings. The modification of both the enable and filter fields are done under the event_mutex, so it is still safe to combine the two. Note: Although Mathieu gave his Acked-by, he would like it documented that the reads of flags are not protected by the mutex. The way the code works, these reads will not break anything, but will have a residual effect. Since this behavior is the same even before this patch, describing this situation is left to another patch, as this patch does not change the behavior, but just brought it to Mathieu's attention. v2: Updated the event trace self test to for this change.
