Linus Torvalds 23859ae444 Fix synthetic event "strcat" overrun
New synthetic event code used strcat() and miscalculated the ending, causing
 the concatenation to write beyond the allocated memory.
 
 Instead of using strncat(), the code is switched over to seq_buf which has
 all the mechanisms in place to protect against writing more than what is
 allocated, and cleans up the code a bit.
