cleanup: Deadlock checker is no longer called from signal handler Clean up a few leftovers from when the deadlock checker was called from signal handler. We stopped doing that in commit 6753333f55, in year 2015.
- CheckDeadLock can return a return value directly to the caller, there's no need to use a global variable for that. - Remove outdated comments that claimed that CheckDeadLock "signals ProcSleep". - It should be OK to ereport() from DeadLockCheck now. I considered getting rid of InitDeadLockChecking() and moving the workspace allocations into DeadLockCheck, but it's still good to avoid doing the allocations while we're holding all the partition locks. So just update the comment to give that as the reason we do the allocations up front.
