The server has 1228 mentions of "_inlock" functions in 133 files, including declarations, calls, and comments. These mentions should be transitioned to take/pass a mongo::WithLock argument, instead, as defined in util/concurrency/with_lock.h, to improve static error detection.

Adoption can be incremental, per function, per file, or per subsystem. Because usage of the "*_inlock" naming convention is primarily confined to private member functions, uses of any particular such name are confined to a few files, most commonly two.

In any case, no new "_inlock" functions should be created.
