// Lock places an advisory write lock on the file, blocking until it can be
// locked.
//
// If Lock returns nil, no other process will be able to place a read or write
// lock on the file until this process exits, closes f, or calls Unlock on it.
//
// If f's descriptor is already read- or write-locked, the behavior of Lock is
// unspecified.
//

// rank.
//
// Internal ranking: as an implementation detail, rwmutex uses two mutexes:
// rLock and wLock. These have lock order requirements: wLock must be locked
// before rLock. This also needs to be represented in the lock rank.
//
// Semantic ranking is represented by acquiring readRank during read lock and
// writeRank during write lock.
//

You can also disable locking on a specific configuration.
This can be useful if a plugin configured locking on all configurations but you happen to add one that should not be locked.
