This picks up tokio-rs/tracing#1247, tokio-rs/tracing#1248,
tokio-rs/tracing#1251, and tokio-rs/tracing#1254. Collectively, these
changes should result in a significant performance improvement when
using
tracing-log
's compatibility layer for converting legacylog
records to
tracing
events.Since we have some dependencies which use the
log
crate, this shouldhopefully reduce the overhead of those dependencies' logging. I'm not
sure how much
log
we have in the hot path by this point, but it'sprobably a good idea to pick up the change regardless.
