Subject[PATCH -next] blktrace.c: Use blk_trace_bio_get_cgid inside blk_add_trace_bio
Date
instead of passing cgid as a parameter.

Signed-off-by: Marcos Paulo de Souza <marcos.souza.org@gmail.com>

Discovered when checking the missing documentation of cgid in blk_add_trace_bio
function when running make pdfdocs.
