Merge tag 'trace-seq-file-cleanup' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace into for-next
Pull the beginning of seq_file cleanup from Steven: "I'm looking to clean up the seq_file code and to eventually merge the trace_seq code with seq_file as well, since they basically do the same thing. Part of this process is to remove the return code of seq_printf() and friends as they are rather inconsistent. It is better to use the new function seq_has_overflowed() if you want to stop processing when the buffer is full. Note, if the buffer is full, the seq_file code will throw away the contents, allocate a bigger buffer, and then call your code again to fill in the data. The only thing that breaking out of the function early does is to save a little time which is probably never noticed. I started with patches from Joe Perches and modified them as well. There's many more places that need to be updated before we can convert seq_printf() and friends to return void. But this patch set introduces the seq_has_overflowed() and does some initial updates."
