* fix up g++ 11 warnings for unused return values
* Add opensuse/leap:15.2 CI build
* Add __attribute__((used)) for template functions
openSUSE/leap gcc on Release build seems to be aggressively
removing templates that are actually required, the used attribute
will force the compiler to leave them in.
* Update docs on io_scheduler for inline processing
Support gcc 10.3.1 (fedora 33 updated)
Update ci.yml to run fedora 32,33,34 and support both
gcc 10.2.1 and 10.3.1
* fedora 32 -> gcc-c++ drop version
* Update ci.yml and test_latch.cpp
* Add coro::mutex example to readme
* explicit lock_operation ctor
* lock_operation await_ready() uses try_lock
This allows for the lock operation to skip await_suspend() entirely
if the lock was unlocked.
* udp_peer!
I hope using the udp peer makes sense on how udp packets are
sent and received now. Time will tell!
* Fix broken benchmark tcp server listening race condition
See issue for more details, in general attempting to
implement a coro::thread_pool exposed that the coro::sync_wait
and coro::when_all only worked if the coroutines executed on
that same thread. They should now possibly have the ability
to execute on another thread, to be determined in a later issue.
