While reviewing vmscan tracing events, I realized all functions which establish paired tracepoints (one at the beginning and another at the end of the function block) were following this naming pattern:
<tracepoint-name>_begin
<tarcepoint-name>_end
However, the 'beginning' tracing event for shrink_slab() did not follow the aforementioned naming pattern. This patch renames that trace event to adjust this naming inconsistency.
