Introduced short-term lock for UMS internal state
Added mUsersLock - short-term lock for internal state, when interaction and
synchronization with PM is not required. Modifications to mUsers and
mRemovingUserIds must be guarded by 3 locks: mInstallLock, mPackagesLock and
mUsersLock. While reads can use mUsersLock.
Testing revealed that the following methods in UMS often cause contention:
- exists
- getUserInfo
- getProfileParent
They all now use a short-term lock mUsersLock for reads.
